If you have free reign in your room, have you tried setting up your system on a diagonal? So your back would be to one corner, you’d be facing the opposite corner, and the speakers would be along each of the two walls flanking the corner that you’re facing. They can be very close to these walls because the backwave reflection path is not right straight at you. This setup geometry can result in longer reflection path lengths than a conventional setup geometry, thereby mimicing some of the behavior of a larger room.
