There are some very interesting options on the table. First, to answer Deb's question on the crossover, I was planning on a 1000 watt 4ohm version from Ralph Patterson Audio (similar to the one in your cab). I wrote to Ralph concerning this and he said he could make one at what I think is a very fair cost.
Also, if Robby's 3/4" Nidacore 1212/6/1 cab weighs 52 lbs. using the heavier Nidacore panels (0.97 lbs/ft2), a 1212/66 could very well come in about 55 lbs. Perhaps the edge treatment isn't as big a deal as I'm thinking it might be.
On the foam, that square law relation between thickness and strength is interesting. Adding 1/4" to double the strength has big implications if you need it. I just want to keep the box size manageable so as not to be too bulky to grapple. 34" high (any taller won't load right into my packed SUV) and 24" wide are my hard constraints. One of the details I haven't figured out is how to glass that mid chamber. Would you just glass the back of the baffle, put the speaker mounting hardware in place, glue the mid chamber and internal braces in place, then glass the cab interior?
