So maybe a Canopy style backhaul would be the better choice?

Fred, a guy on the UBNT site was offering some RF shields for the UBNT 
sectors.   Those, combined with spacing and screening and grounding, 
appeared to bring the RXSL down low enough to actually put the same 
frequencies on the same tower.    Or, if it were a building or water tank,

But, Airmax does not provide immunity from self interference on its own.   I

know, I tried.   I put a backhaul and sector on the same frequency and when 
the sector was busy, it seriously degraded the backhaul's throughput.   And 
vice versa.
