Actually I just noticed that the left rear side of the room will have a bumped-in corner, so if you were to shorten the hallway to match (or even be a bit longer) you would have room for a door to the toy storage area, wouldn't have to cut any space out of the HVAC/toy room, and would still open up the space to the RHS of the rear couch enough to make (IMO) a difference in sound.

You would also be able to move the right rear speaker over to the right a few more feet (as long as HT door had some kind of stop so you didn't hit it, or if the HT door opened outward with hinge on the left) which would balance the sound a bit more.

EDIT - if you felt like going overboard with sound control you could also put a second door at the entrance to the hallway. The local gun club has a double door arrangement like that and it really makes a difference in the amount of sound that gets out.
