I haven't really thought this through, but if I were doing upper-bass horns again, especially if cut using a numerically controlled router, I might consider making tham oval, which would permit going for a horn with a lower cutoff (larger mouth) while not requiring that you raise the MF horn(s).
Though the image below shows an upper-MF horn, the same could be applied to upper-bass (minus of course that big square flange):

I should add that going for a lower cutoff on the upper bass horn may not be desirable; depending on your MF solution, the upper-bass horn may be asked to do some lower-MF as well. How do you plan on handling MF (dedicated lower-MF and upper-MF horns, or a single MF horn)? The answer to this question might also influence your selection of profile (tractrix vs a slower flare) for upper-bass.
Best of luck with the project,
