There are too many variables for anyone to predict IMO. Why not listen, move forward listen, etc, in 6" steps. Once you find the point where performance improves you could take smaller steps to pin point.
The less is toe in the less is the cabinet a problem. Yours are mono poles, right? (Above the bass, of course.)
At 2014 Newport THE Show, one of the few rooms I really enjoyed besides our own was HR programs (exclusively I believe) > EAR Yoshino tubes > $80k/pr Marten ceramic cone/dome speakers. Yes, of course the gear is good. But I suspect one of the reasons the reverberant field performance was so exceptional (for a mono pole) is because he had the speakers about 1/3rd into the room.
Mono poles need less front wall spacing than the big bad Sound Labs, but the best I ever heard those exceptional speakers (in stereo) was the late Bob Crump's CES display where the stats were about 1/3rd into the room.
Anything reflecting earlier than about 10ms (11.3 feet) vs. on-axis direct signal is generally not a good thing. That's why dipoles and bipoles like about 5.5' behind them (source to front wall back speaker = 11' or 10ms).
