So I understand the MP-E 65 can go to 5X... but what would I need to get my 100mm f2.8L macro to magnify by that much? How many extension tubes and extenders?

You'd need 16 of the EF 25 extension tubes to achieve 5x magnification.  Or six tubes and a 2x extender. 

FYI, the MP-E 65 takes extenders, makes for an easy 10x mag.

And you can stack the extenders (some of them anyway)! I've taken it to 28x, although it's diminishing returns, as you'd expect.
Current equipment: 5Ds, 5D mark III, 50D, 24-105L, MP-E, 70-200 f/2.8L II, 100L macro, 500L IS II; 1.4xIII + 2x III extenders; 600EX-RT.
Former equipment includes: 300D; EOS-M, EF-M 18-55, Samyang 14mm f/2.8, EF 35 f/2 IS, 70-200L f/4 non-IS, 85L II, Sigma 180 macro, 200L 2.8, 400L 5.6

I wonder... Would it be less expensive to get a microscope and find a way to connect the camera rather than all the extenders and tubes?

I've also found that with ETs the length of the lens barrel is an important factor. Sometimes you get the focus so close that it lies within the lens barrel so the combination becomes unusable. In those cases TC will give you mag at the cost of aberrations.

Tangent: Just to satisfy my curiosity I also experimented with using the 24 STM on the 6D with a 2xTC and ET combinations. Silly I know, but when curiosity compels...

I use both the MP-E and a microscope. They have different strengths and weaknesses. You might well have an extender and/or extension tubes, so if you get the MP-E you can play around with the combinations if you want; a microscope and camera adaptor is a more specialist piece of kit, though they can be obtained surprisingly cheaply. A microscope is much less portable, of course. Easier to go to much higher magnifications, but cheaper objectives are much less optically good than the MP-E. And good ones can be expensive! Swings and roundabouts.

"Rathaus Basel" image is fantastic. Really highlights the merits of the TS-E. Did you make a note of the tilt and shift settings that you used? Also, did you use any accessories (e.g. geared tripod, geared head, angle finder,field monitor, mirror...etc) to help with composing/shooting in an upwards direction?

With the Mantis shot did you use a flash-modifier?

The Arc de Triomphe shot looks a bit over-corrected. When I first got my TS-E I found the Schneider optics guide (http://www.schneideroptics.com/pdfs/photo/PC-TS%20Anleitung%201-12%20en.PDF) which on page 12 recommends methods to retaining some residual keystone for more natural-to-the-eye geometry.

Personally, I feel it distracts from the picture. But then photographers are distracted by many things that most people would never think about. The residual keystone thing may just be a matter of taste.

I think keystone correction is a bit like going for the first kiss:

Thanks for the feedback!

I don't generally note down the T/S settings I use, encoders would be nice.  That shot of the town hall in Basel, Switzerland used quite a bit of shift ('downward' to get apparently closer to the facade) and just a bit of tilt. No accessories, just my travel tripod (RRS TQC-14 + BH-30 LR).

For the mantis in our back yard, I had the StoFen diffusers on the MT-24 EX heads.

Perhaps you're right on the keystoning - IIRC, I corrected a bit further with DxO, maybe too much.
