So I am wondering. Given that the frequency would drop in the 20s do you believe this type of setup would pressurize a room equal to or better than the 20.7? I assume people that purchase Maggie's love planar bass. It seems this would be an excellent option at a very affordable cost assuming amplification is covered for the DMWs.

No. The DWMs will not give you 20.7 quality bass, nor extension. Nor would they match a Tympani IVa. What they will do is provide audible extension below the resonance freq.
As Roger noted planars don't actually "pressurize" a room the way a sealed dynamic speaker would, but given sufficient power you can get deep powerful impactful tight and dynamic bass. The bigger the speaker and the more DWMs the more bass output and extension you get.
If you want big planar bass cheap then build a frame to take a stack of used MMGs - take their buttons out and bypass/disconnect the tweeters 4 or 5 MMGs per side stacked sideways should give you more bass than you can imagine. Same if you do this with a stack of DWMs just that it is a more costly option.
You can't remove the buttons......and you wouldn't want to even if you could. The speakers would sound horrible.

Just for use as bass panels. Think planar subwoofer.
Dipol speakers will not pressurize a room. I still do not believe you get anything like flat to 20 Hz from any setup of Magnepan speakers. The roll-off below the lowest resonant frequency will be there and there is almost no room gain from a dipol.
What apparently happens is that the baffles and proximate sidewall couple, shifting Fequal, so the 3 dB point really can move lower than it otherwise would. But the effect is room and setup dependent, which is why Magnepan makes no claims -- it's basically a fortuitous occurrence that surprised them when they first discovered it.
