I don't see any obvious why it wouldn't work. MU-MIMO might not work too well, but you probably don't care too much about that in this case anyway.
I think I would probably put the radio half way between the two antennas so that you can have equal loss both of them... that way you can set the tx power on the radio higher to compensate for the cable loss.
