One could take some sandpaper to the inside of the clamp area, widen the diameter. Or is that a Really Bad Idea? Please consider your answer, and not just a knee-jerk 'dear god no!'

It's a bad idea. You're taking material out of a thing designed to have that much material, which isn't a huge deal for a shifter - you just lose a shifter - but if you squeeze a brake lever going downhill at 25mph and the clamp pops instead of pads contacting rim or disc? Buddy you got TROUBLE.

I have “opened up” the clamp on MTB shifters to use on Drops...it works just ok...if you had an accurate way to enlarge the diameter it would be better, If you don’t get them right, they slip. I agree with Joe Bernard, there is so much “leverage” on the brake lever perch that you might stress it and snap at an inopportune moment.
