Hey Jmt, just browsing through and came across your system...well done!
I had an identical size room years ago and used NHT Super Ones (2 way monitor 6" mid-bass driver). I thought I would upgrade to floorstanders and got Monitor Audio Silver 5i speakers (2.5 way with dual 5" mid-bass drivers).
In my room the NHTs actually sounded better as the Monitor Audios were simply too much speaker for the room. Don't give up on high quality two way monitors in that size room.
Two other things I did that I think really worked out well; first was to remove the closet door and add custom shelving for media storage, second was to set the system up so that the speakers fired across the diagonal of the room.
The diagonal placing really paid off well.
