I applaud your willingness to try things which others would say "can't" be done! I myself have many times explored less than optimum options and found terrific enjoyment. Kudos on going after the speakers you WANT, regardless of the opinion that they WON'T work in your room. I'll bet you are enjoying them immensely! That is precisely what I would do, realizing that the benefits would outweigh the drawbacks.
I see so much of myself years ago in your system. I would have made it work, just as you have. THAT's so much of the glory of this hobby, going after the dream, the enjoyment of making a system and room work. I think others should take encouragement from your efforts, to not let less than ideal positioning, etc. stop the exploration. I'm quite sure you have plenty of joy listening to the dream speakers you always wanted. :)
I owned Maggie 1.6QR for a while, so I know what you are experiencing, and it's great to run panel speakers. Nice go with the supplemental sub. You can refine this rig as much as you want; in this intimate setting you will hear every improvement.
A couple thoughts...
What is the grey device behind the left speaker? Is this an electronics related device? Related to the space behind the speakers, you may wish to consider making some sound panels from sheets of dense insulation; you can get such from suppliers, look on line. You may enjoy the effect of diminishing the back reflected wave off the head wall. Take a look at my front corners where i have placed panels to reduce the bounce from the backward directed wave.
Again, superb! Your rig touches so many memories and the simple joy of exploration which I love in audiophilia!
