a filter driver would work here....BUT windows acceleration algorithm is
applied at a higher level in USER (in the raw input thread) after all the
different mouse streams have been merged into one stream. If you can turn
off window's accleration algorithm (don't know how to do that), you can
implement the algorithm on a per mouse basis in your filter.

As for supporting a 5 button vs any other mouse, as a filter, it doesn't
matter. you sit on top of the device and modify its X and Y deltas and
leave the other data alone.
