I am intending to do a similar experiment with a friend's Focal Nova Utopia with the mini fridge bass units and my Neo8 + ribbon mid/tweet sections.
Generally speaking, a braced set of T IV bass panels is not uncompetitive with the Focal bass given sufficient power to the maggies they do a very convincing rendition of organ foot pedals. Where they lack in comparison to the well done box woofers is with percussive bass. That pounding sensation just never happens.
I recently tried out my converted Vandy 2c subs with Aura 8" Neo driver and 10" bass using both speakers on one side vs. bass panels on the other. (equivalent to 2 13" bass units) and tested to see where the bass would swing to the Vandy sub's direction, (calibrated level settings at 100hz) and it was only in the lowest contrabass notes and organ. But playing loud bass heavy dynamic music the vandy subs started compressing and rattling while the bass panels were just fine. And the music did not pull to the sub's side at all.
So I think the issue is not having enough radiating area on the 3.x models and the need for sturdy bracing, and really big power (I use a Crown 5002). The difference in bass performance with the big maggies on Mye stands or other bracing and left to themselves is vast. It is like adding a large subwoofer. The dynamic limitations you are speaking of are easily surmounted with bracing and ample power . - and a big bass panel...

That could be cool. Just try to cross high around 250 for comparison. Unlike pure sub, JL like T-Rex thumping drivers-Focal 13WX inch Audiom woofer is fast and musical, able to sing very high and I think was crossed around 250hz in both WILSON Maxx and Utopia.Not sure about biamping on Utopia though....Some 7 or 8 years ago I helped my friend to build sub with 11WX woofer Focal audiom to mate it with 3.7---was not bad.
I have line level XOs to play with so can tune the same way I have with the bass panels.
