The brightness and midrange issues with your present setup may be caused by uncontrolled early reflections, RF noise, mechanical chatter in your equipment support, or a combination.With your present best placement for bass, figure out the first-reflection areas on the side walls. These are the places where you would see the images of the tweeters if the walls were covered with mirrors. Experiment with folded blankets on these areas to see if the brightness problem improves.
Another area to treat is the place where you would see your reflection if the wall behind the speakers were covered with mirrors. This will affect the sound-stage more than the brightness, but it may help.
Mechanical chatter is caused by casual contact of hard materials. I've had it affect the treble in my system, so I'm including it for completeness.
RF noise is a widespread problem in better home audio systems. It affects all frequencies, but is most noticeable as a sense of brightness, fore-shortened sound-stage, and a dry and uninvolving midrange. The MG-3.6s will not make this problem better, and may make it worse.
If placement and wall treatment do not completely cure your brightness and midrange problems, and even leave you with a sense of missing treble information from the quasi-ribbon tweeters, then it is likely you have RF noise issues and would not get the benefit of the MG-3.6s. However, if you do get the speakers and suffer from the problem, there are things you can do to ameliorate the problem and improve the performance. How much this costs depends on your willingess to use a soldering iron.

Your suggestions have been very valuable. The biggest problem I am facing with the speakers pulled into the room is that they obstruct viewing the projector screen from any angle except the listening position which is a major WAF issue. This will only get worse with the 3.6's larger size. I have to now figure out a way to be able to pull the maggies in during critical listening which is not easy as I have marble blocks on the stands behind. I guess the only other option is to build another room!I have put my 3.6 purchase on hold for now till I can figure out placement. In the meantime, if I can convince the dealer with the ML's to send me the pair on demo, will try that option. I don't know how susceptible those are to room placements, will have to listen.
I had corresponded with Mye Audio about a year ago but shipping to where I am (India) was super expensive so I dropped the idea. Will probably make a pair of my own and experiment.
than the Magnepan. All dipole speakers are sensitive to location in the room.An alternative if you ever do get the true-ribbon Magnepans is to turn them by 90 degrees so that the edges are facing forward. This works because the ribbons have nearly 180-degree dispersion. I have my MG-20s oriented this way. This opens up the area between the speakers, but they protrude farther into the room. The centers of the bass panel sections are located at the Cardas positions.
I understand about the shipping expense for Mye stands. I'm guessing the cost for Maggies and your electronics over there is also much higher then here in the US.Only the lucky few have a perfect, dedicated, listening rooms over which they have complete control. The the rest of us have to make compromises to one degree or another. The goal is to make the compromises which give you the best results you can get. Hey, you can only do your best.
Based on everything you've said to this point as well as the updated room measurements and the screen issue, I would agree to putting the 3.6's on hold for the moment. Work on getting the best you can from the 1.6's. Good luck!
