Theoretically speaking, yes, WEXT could be extended to do this with some
kind of scan parameter that indicates which 64 kB block is requested.
However, I would not suggest going there and I would probably object to
a patch that tries to do this either in the kernel or in wpa_supplicant
for that matter.

If you really end up hitting a case that does not work reasonably well
with 64 kB fix in user space, I would suggest looking into the
cfg80211/nl80211 scan stuff. The only additional thing it needs in such
an environment is to get better optimized data structure (for which,
there is already a proposed implementation, too).
