Wow, thats quite a few placement options, and a lot of moving heavy speakers. You have some ambition. Do you have separate dsp and amp channels for each woofer? That may determine just how useful various placements can be, as it will allow independent time alignments.
Disclaimer: There are many approaches to subwoofer placement and integration, this is just my understanding of the most beneficial workflow.
The graph I’m asking you for would be (and was) step one for me. The reasoning is it demonstrates the compatibility of the dev’s and marty’s, completely independent of placements. The relative phasing of the sub outputs won’t change with room placement, although the magnitude and total phase will. Basically, if you get destructive summation at any certain frequency range, it will always be destructive with placement, though the resulting summation magnitude will vary with room response of the chosen locations.
Then the second step for me would be messing with placement. Or it would be if I had more than 1 possible location for each sub. I’m actually lucky enough to have enough dsp channels and amp flexibility to individually control each sub. However, my lack of placement options, and my preference for visual symmetry completely nullify it. I plan to use absolute headroom and EQ to fix room modes, lol. At least I don’t have any nulls.
And yes, my room is far from ideal, like yours and most here.
EDIT: the graph definitely shows potential, assuming you will be using 4-6 of the placement options. Out of curiosity, which two are avoiding the null near 40hz?
