What if - interchengeable sensors

I would have to say that instead of "interchangable sensors", the best choice would be, a sensor that could be tailored to each shooting need.
I know it has already been rumored with a couple of camera bodies, but IF Canon made a (for the sake of arguement) a 28mp full frame sensor that could DO several different things.
IE, be programmed to...
1. Be a 28mp full frame, high (12800, example) ISO 4-5fps sensor (silky smooth images)
2. Be a 24mp full frame, low ISO (6400, emample), 10-12fps sensor (not so silky smooth, but trade-off for super speed)
3. Be a 18mp APS-H sensor (1.3 crop) low ISO high speed sensor, 16+fps
4. Be a 16mp APS-C sensor (1.6 crop) low ISO super high speed senor, 18+fps...
Low mp (14mp? 16mp?) and extremely silky smooth images at very high ISO (12800+) ???
You get the idea. One sensor that can be programmed to do whatever you wanted. There are times you want a full frame, "silky smooth" image (with low fps) and there are times you want the reach of a APS-C senor with super frame frates (I.E. 7D) Combine this with a body that can accept EF AND EF-s lenses and you get whatever you want!
You can't have it all, but I believe the technology exists that Canon COULD produce a multipurpose camera that could do allot of this and more.
"DIGIC" could be programmed to do each of these things. Trade one quality for another kind of thing... I also believe that if Canon went back to the "still" camera (and I hope they do, just MO) and took out video shooting you could squeeze allot of different sensor resolution programs in it's place. I would BUY this camera!
Just my 2 cents.

What you propose would be the best and I'd love it too. But here we'd have interpolation issues which I really don't Know how to avoid.
Does anybody know if there were any tries of designing another type of sensor with some other than linear or rectangular rgb subpixels arrangement - ie in triangular arrangement? Or maybe splitting rgb dots in one dot (ie placing r, g and b subpixels over each other - some kind of layers)?
(Edited some grammar and meaning)

I don't think that we'll see an interchangeable sensor system in the DSLR world. While it is quite common with medium format it just doesn't seem like a good solution for DSLRs.
Just think about the requirements for a moment.
If the sensor were interchangeable the image processor(s) would have to be interchangeable, too, since they won't scale for very long.
If we have interchangeable sensors and image processors we need to introduce lots of software onto the camera OR give this interchangeable module its own set of software that melely interfaces with the body - the latter is probably the better option since it will scale better into the future.
The resulting camera would be much more complex than anything currently on the market though and it would be rather complex to develop. The body could be rather cheap of course - say 500-700 bucks. The sensor(s) would probably come at a pretty hefty price though since it will carry all the complex electronics and it would be a very delicate part prone to damage until it is tightly assembled to the back of the camera.
What if they wanted to introduce a new feature though (as in actually new). They'd ever need to build the camera in a way that its future-proof-expandable in every direction or you'd still need a new body every now and then (with current development, we could be speaking of a new body every other sensor generation), which would kind of ridicule the whole concept unless this whole concept were to be developed for a niche market like medium format.

Well, DSLR's do this in principal already. You can choose a 6mp, 8mp, or 10mp (as the case may be) sized image already from most digital cameras. As you cropped down the image size (by simply selecting the pixels needed) the resolution would become whatever fit inside that particular crop. You would just take a image from the inside pixels, nothing more. Also being that it would be a smaller image, the DIGIC could process it faster. You would give up image quality for speed or visa versa.
The camera would only need ONE sensor (IE full frame ??mp) and you would simply use the pixels you needed. (full frame, APS-H or APS-C) I would imagine that even if the camera cost a bit more than normal, I bet several people would buy it because they would only need ONE camera for multiple shooting needs.
Look at it this way, my 7D can take HD video right? HD video is 1280 x 720. My sensor is capable of taking a still at a resolution of 5184 x 3456. So if my 7D can take a HD video at a smaller resolution at 30fps and process it quickly enough for video needs then my camera could also be programmed to take a photo at whatever resolution I choose! This is about programming the DIGIC to process the image, nothing more. I realize that there is more to it than that, but in principle it is that simple.

Ricoh is offering that right now: The Ricoh GXR. The lens and sensor is one easily replaced module.marekjoz said:
It allows for better optimization between lens and sensor and it should allow for economical specials like high resolution B&W without Bayer pixel color filters, color interpolation software etc.
http://www.ricoh.com/r_dc/gxr/
I would buy one right now if they had an unfiltered B&W module available.
