It would need to be one of the better-than-apple Language Cards that
didn't require the RAM umbilical, but other than that I don't see why
not.

/INH is asserted by an expansion card in response to some event; in
the case of a language card, it's during an access to $D000-$FFFF
whilst the language card memory is active.

On a standard Apple ][ or ][+ /INH only deactivates address decoding
for the onboard ROM. The IIe and IIgs however disable *all*
motherboard address decoding during /INH. Jim Sather's book describes
a very straightforward modification that will cause a standard Apple]
[ to behave the same way.
