Its a lot of futzing to be certain, but worth experimenting if aiming it into the corner or towards the hall makes much difference. I'm sure it will make a little, though it might not end up being audible.
I always find that avoiding the worst effect of corner loading requires about 2' minimum. But if it works well in your home, no reason not too. just listen carefully and watch out for muddiness. Check your audyssey graphs, of course, and see if you can't smooth it out a bit the manual way.
