I've got 18" aftermarket wheels and recently had a bent rim in the passenger rear due to a bad pothole.

So far it's driveable, but I was a good distance away from home when I found the bend, and only had a space saver spare (with my upgraded brakes, I use a Supra TT spare to save weight).

Question for the wheel gurus: For those folks who have larger-than-stock wheels, what "bad happens" when you have to use a smaller spare wheel for an extended period of time?

Different issues for front and rear? I'm not only concerned about stock impacts, but any issues with LSD gears, TC, etc.

Know some friends with flatbeds tow trucks...

If that doesn't work for you, you could always buy some inexpensive 18" wheel (with good brake clearance) and just install an inexpensive tire on there and use that as your spare...

For me, if one of my front tires blew out, I would do this and then adjust my coilover UP 1/2" (cuz that the difference between a stock height wheel and my 20" setup)...it would look a little funny but it would drive OK (wouldn't lean weird...)

Yet another advantage of running coilovers...

As for the impact on the other things (TC, etc., etc.), I wouldn't recommend doing a crazy canyon run after you put on your spare...I would just drive safely afterwards.

I haven't tried to fit a "20" profile (like the standard 20" setup or the "Fat" 19" setup) into the spare tire well...it may or may not fit...
