Thoughts? 26' rectangular room -- 2 channel on one short wall, 5.1 on the other

I'm interested in your comments or experience about this proposal to combine 2 channel listening with home theater. I have good tube amps, sources, speakers and another system with a modest AVR and A/V capable speakers. I have plenty of subs.

Here's the situation:

I'm about to finish out a basement that is 26' x 16' x 8'.
I was thinking of trying to have the 2 channel on one wall and the A/V on the other wall.
Two couches, back to back, would divide the room and the mid point.

Doing it this way, I would get the 2 channel set up to optimize the sound, hopefully in conjunction with the home theater, which would only need to accommodate a 65" OLED TV.

I've posted a photo of a diagram (including ideas about dedicated lines — comments welcome there, too) on my system page: https://systems.audiogon.com/systems/9064/edit

The other way to do it would to be to have everything on one wall. I'm less inclined to do things this way.

Thoughts?

Thanks.
