Best driver placement for 4 drivers

I did think that there was a technical reason for keeping to a maximum of 2 co-incident drivers tho, and this is why WW MTM WW layouts are so common when using quads of woofers

I had contemplated that... with putting only two mid woofer drivers below the mids and two above, it allows a fairly comfortable fit below, and allows the tweeter to be placed optimally at ear height.

That did cross my mind as I was trying to get off to sleep, I had a quick 2 second look at the 4 drivers placed in a square in Edge last night, and it popped into my head that perhaps it would be interesting to see if offsetting them like in your picture might help flatten the graph.

WW -MTM- WW is how I have ( in my head ) the design of my own big open baffle project, trouble is I do not have a room or hall big enough to actually use my design in and my planned OB also needed subs below 40-60 Hz anyway as the big Jaycar paper coned woofers only have 3.5mm of excursion before reaching mechanical limits ( these are the 12 inch DFR'd woofers - I have a dozen waiting to be used ) they went to $29.99 each so I bought all I could at that price

I think I would need to do something like MW MW TW M M MW MW because of the shape of the tweeter, and do the woofer separate.
Due to the amount of drivers I am using I have kind of resigned myself to using two boxes per side to house them all.
Another option I could put all 4 mid woofers together and put the mid / tweeters on top of the woofer.
