Second this. It may be a bit more barebones on the little features that add up on units like the Denons, but it will make up for it in sound quality. Dirac Live will give you better frequency response and imaging than the other AVRs mentioned here that do not use Dirac.
The slim on-walls up front may really limit things, but it depends on the design.
Maybe there's something I don't know about this room, but if you have 11 inches between each screen for speakers, why can't they be floor standing or stand mount speakers?
Hard (for me) to justify the ML surrounds when Emotiva makes a very similar speaker for 35% of the cost for a pair
. Though, how much output do you need?
Chane will release their A4.4 this year, which should be a solid surround speaker. Keep an eye on those.
I also second the Rythmik FVX15 sub recommendation - and they have a multi-sub discount, so they would actually be $4196 for 4. The best bang for the buck from one of the best sub makers. Though I think you'd be fine with 3. You will need a MiniDSP 2x4 HD to time align the subs.
I do see a problem with the Martin Logan on-walls. Their frequency response extends to only 100Hz due to the thin cabinets. That means choosing a crossover is going to be tough - ideally you want speakers that can perform one octave below your crossover, so a speaker crossed at 80Hz to subs should have a -3dB point of 40Hz. For a speaker capable of only 100Hz, you can do the math, but the highest I would want to go is 120Hz on the crossover, and don't place them near your seats. That means you may be better off with a paper cone Rythmik. I would inquire about that if interested.
