Quick question... has anyone ever attempted, successfully or not, to move the radiator up and/or back a bit so that it isn't quite so smash-able?
Background... I had a Saturn L100 that my brother in law wrecked a while back, so I tore all the doors off, cut a BIG hole in the roof, and turned it into the redneckest go kart anyone around here's ever seen.

Before it eventually died from taking a big drink of water into the engine (I wasn't driving at the time), I pushed the radiator into the front rail of the trailer I dragged it around on. After patching up the holes in the bottom tank with some QuikSteel, I decided to hoist the whole rad up and tilt it back. Being that it had an electric fan and a good bit of flexibility in the hoses, this was no issue at all and totally got it out of harm's way.
My TB is at a good altitude now, but it's a bit scary to peek under the front bumper and see that radiator tank hanging there. It sure would be nice to relocate it.
