"...I am sure some folks here may detect all sorts of audiophile transgressions and even deem some/all of them to be limiting in nature and possibly even the singular constraint that precludes my objective, but if so, that would be unfortunate..."
You have asked a tough question. Don't take this the wrong way but your room looks more like a sports bar than a listening room. I dig it but it probably IS holding you back. I'd love to spend an afternoon at your place moving some things around and getting your system working it's best. I'm not sure why all the hung pictures are not rattling like crazy. Then it hit me. It's a big room and it's not fully energized. So with that in mind I have two suggestions; a) Move up the Focal speaker line and get a larger/better speaker. b) supplement the bass with some subs (a pair of woofer towers would be best but your budget will be blown with the loudspeaker upgrade). I hope that gives you some ideas.
