Unless the Boogie cabinet has an internal wall, I think the internal volume would be different, which is a pretty key design parameter I think??
Has anybody noticed whether there is any construction in the Boogie 1x12 so it would match the internal volume of the TL806? I don't own one, but am thinking of building one to go with my mark iv short head. (and I realized as I was looking at the TL806 plan that it would be 1" too narrow...)
