Its new areas are reached via "teleport"-style move rather than worldmap style move, so it should work with whatever alphabet soup you happen to be using.
interesting work indeed, i hope to try your mod soon (with Xan may be? ) ... just a couple of questions coming up to my mind:
Is this mod compatible with BGT ... i assume yes but i wonder if it adds maps or something similar so that it is unplayable with the Worldmap mod (and so with a mega modification as well).
