Your favorite Electrostatic, Panel spkr

So am i correct, they will be on the 12’ wall, not the 9’

Try the speakers on either wall and see what you prefer. A lot will depend on what speakers you end up with. Dipoles like Maggies will need more space behind them. The JansZen maybe not so much. In fact I think the manufacturer recommends them being closer to the wall behind them. Dynamic speakers will vary too. Some will offer more flexibility in placement than others. This is why I would recommend getting speakers from a manufacturer that offers a home trial.

I currently own Quad ESL 57, Acoustat Model 2 (modified and used with the Acoustat Direct Drive amps), and just picked up a pair of Analysis Audio Epsilon (planar ribbon). There is no substitute for the mid-range in the 57 in my opinion. The Acoustat's and Analysis Audio provide great mid-range as well, but the Quad are not to be outdone in that area. Although the Quad do not have the extension at the extremes of either of the other speakers, I find the bass satisfying enough for my tastes. That being said I ended up bi-amping with an electronic crossover and adding a multiple sub array to my system so none of the speakers drives anything below 100 Hz.

@kgveteran you mentioned two different room sizes in your posts, neither very large. Here are a couple thoughts. The Magnepan LRS comes in easily under your budget, and some of the larger Magnepan speakers are going to fit in your budget as well. If you buy the LRS direct from the factory I believe there is a 30 day trial so you can try before you buy. Another option is the JansZen Carmelita hybrid ESL monitors. Nice foot print but a tad over your budget. JansZen offers a trial period as well. Either of these speakers can be used on the short wall if you prefer. With the Maggies you would have enough money left over to add a couple nice subs and still not compromise your space.

My room is 12' x 20' and all the speakers I mentioned previously work well in it set up on the short wall about 4 ft. into the room. If you intend to put the speakers in your home theater room you could probably get bigger Maggies and still do just fine.

As for your subs using them with the Maggies would be fine. However, I'm a little confused as to the position of them in the room. What I think I understand is you have 4 subs total, two that are positioned somewhere to the left of the listening position and two somewhere to the right. Perhaps you can be more specific as to their positions. I assume you want to leave them in place for the HT set up. Hopefully the addition of the new speakers will allow that to happen.
