Those doors are not going to make things easy to improve over what you have already done.

Is it possible to use the other end of the room for the speakers, or is there a large window there?

Barring that approach, and a more conventional arrangement of sound absorbers, there are a few things you could do.

Use the other two sound panels in the rug area, and use them to cover as much of the still bare wall (not covered by the rug) as possible.

Make some DIY corner tunes (do a search) for the front corners, and move the sound panels along the top rear wall toward the middle to make room for the DIY corner tunes.

It looks like you have a window on the left of the left speaker, and a wall on the right of the right speaker, this can be a problem for imaging, and the best way to try and 'equalize' the two side walls acoustically, would be to use some DIY room lens at each location.

Treating the whole rear wall, while it may do some good, should not be done with a too thin layer all over, which is what it sounds like you are proposing. The spot approach with thicker panel's or absorbers is better. In your case, there is so much 'door' on the rear wall, that it just makes it harder to do some good. The doors are unbalanced too, and this is also a problem for the remaining space and where to place the absorbers,
Symmetry is best, and even if it means less total absorbing material.

Removing drywall to install fiberglass can work, it is a 'brute-force' approach, but it's effectivenes is much less than that of the Tube Traps, unless you make the amount (depth) of fiberglass as deep as 6-8", instead of the 2-3" that a 2X4 depth allows. Thus, in order for it to be very effective, you would need to "lose" some room volume, by bringing the surface of the fiberglass covering out into ther room.

Yeah, I know, nothing really good is ever easy.

Try replacing the rug with an nearly equal area of thick fiberglass (at least 6") temporarily, center it with respect to the speakers and the room, and see if that does it for you acoustically.

Good luck!
