"the fact that the voice coils heat up thus increasing resistance which in turn changes the response of passive crossovers"
Well... That would change the response of the system due to the DC impedance shift of the load but not that of the crossover itself. Of course it will heat up also but probably not as much or as fast.
What I found fascinating about your post is you have me wondering if this is the reason or at least part thereof that many listeners seem to prefer a more matched source such as open-loop tubes/transformers. That should largely dominate the the thermal response of the speakers, especially the woofers. Of course it also introduces another artifact: worse damping. But I wonder if that might not be a good thing in many case?
I've orders of magnitude more power than I need so I think I'll try some build-out resistors just for fun. My room is pretty dry acoustically which I think is good in general but maybe wetter woofers would work wonders...
