Applications are not the problem, for that you only have to edit few lines in
and probably all references from version 2.1-update1 to 2.2, e.g.:
Then you should be able to install android 2.2 apps...
As far as the whole system partition is concerned, there might be some dependencies for some libraries that require parts of the new kernel, you are free to try that out... Just don't forget to create a nandroid backup
Also the "new"-jit-speed up is already possible with the 2.1, it's just buggy as hell
Wifi tether might work, for the same reason that android-wifi-tether works with milestone with only su permissions, because the kernel for 2.0 included the necessary module(s) : )
