As far as I can tell, that will not work, because I want to have
multiple station devices per radio, and have each of them be able to
use a different configuration.  So, one station may be /g, and
another /n and another /AC.  Same with APs.  In addition, some
stations may want to use all available rates for their mode, and
others may want to use a fixed rate or subset of available rates.

So let's agree that we're splitting the *used* rates (which we have
today) and the *advertised* rates/modes/...

Even if we can't modify the wiphy capabilities, perhaps we could still
handle it more consistently at mac80211 level, e.g. by introducing and
using "sdata->capa.bands" (and similar for all the other wiphy
capabilities you want to manipulate), and then allowing that to point
to something modified?
