There's a few issues... first, as dr crouble mentioned, it would still be the same size sensor and regardless how much pixels it has, costs wont be any cheaper to produce and you wont have the superior resolution of 21mp (for lets say 4k video comes out, etc... It's much easier for Mr Canon (not that he will) but to throw in a patch or firmware to record that size vs recreating the sensor (again).
Secondly, the bigger pixels, the less noise is sorta a myth... With that thinking, the 10D/20D should have less noise than the 7D, but the 10D got noise past iso 200... (But in it's defense it was actually very close to film tolerances and most photographers using it had a film background so we didn't think anything of it). Plus, with the smaller pixels you have finer resolution hence you can SEE the noise easier whereas the noise on lower resolution cameras would have to be big enough to take up the majority of said pixel to show, and with those cameras it didn't take much.
Now with that out of the way, they definitely can put together a barebones no frills super video camera dslr but they would have to make it at a price point (full frame) and cheap enough to produce where it would be profitable and where they are comfortable that it would have enough of a demand to warrant it. Dont forget struggles including jello cam/rolling shutter, frame rates, buffer and recording limitations, sound options, etc... I couldn't see that kinda camera until they get those dslr quirks sorted out. If they're going to invest in creating a camera they dont want any of these issues to ruin the camera.
