Well, apart from the behaviour of olsr (which i don't actually know of),
 bleedover isn't a problem that couldn't be solved. It would call for
quite good filters though. Those filters would have to have high
Q-factors which is all but impossible to achieve. In Amateur Radio there
actually are repeaters with channel shifts of a little more than 20 MHz
@2.3GHz, some even operate receiver and transmitter on the same antenna
simultaneously. So i'd suggest to contact local radio amateurs and ask
them for suggestions.
