I have several wall-facing installs where the space between DTS-10 and wall was between 5" and 6" and the results were more than satisfactory!
In the area covered by/in the shadow of the body of the DTS-10, I would omit the oc703 and tile the oc703 around the DTS-10 outline, where it could mitigate early reflections from other speakers.
That wall had better be stout though, or you may expect some losses from the wall acting partially like a diaphragm/membrane. Of course, this is generally true of ordinary drywall walls in an HT, but having the wall directly reflect all the energy from the port makes for a worst case scenario...
That being noted however, in the spaces where we chose wall-facing port deployment, that orientation created the highest SPL AND the smoothest overall frequencey response, before EQ.
The effect of tightening the gap too tight, besides possible lower SPL, you may end up getting audible chuffing from the port.
Definitely worth trying it in your setup, IMO.
