Don't be afraid to try.  We are doing it already.  Two radios, 1 antenna.  I've
heard people telling me, no no no, it won't work, it will be bad, you will have
problems.  But, I tried it, it works, no problems yet (only set it up a couple
days ago).  I've even taken two radios, back to back, via coax, no antennas,
and they work just fine.  Then, two radios, into a splitter, with one of the
radios associated with the other radio, so the client device is scanning the
area using the same antenna as the transmitter, yet I can login to it without
utilizing an ethernet port.

If you do it, couple suggestions:
1 - Use channels that are separated as far apart as possible (ie, channel 1 and
11 or 1 and 14 if your country allows it).
2 - If you use an amp (yes, we've tried it with a single amp and single
antenna, sharing 2 radios), don't use a tunable amp, because you'll have to use
a wider part of the spectrum to utilize both radios at the same time, without
packet loss due to collisions (ie, self-interference).
