That's a reasonable approach, and it isn't too difficult either - somebody motivated enough could do a patch... Hmm, I think I have a question and a suggestion here: what is it you have problem with minstrel ? I don't care which one but both works well enough here. Maybe you need that sorted instead. The other thing is, you can probably patch compat-wireless to do something similiar or at least experiment with it, as long as your kernel is configured with most of them as modules. Switching compat-wireless is quite easy, and particularly with the 'driver-select rtl818x' option you just rebuild about 6 kernel modules instead of the usual 50+, which makes it quite quick and painless.
