I was actually wondering about this, since TDM does *not* alter any of the data file, and merely adds shipsets and AI files, unless a small change sneaked in the 3.40 release, altering a line checked by the game or another. In this case, you would indeed need the mod to play your turns.

Bar such a possible chance, I would expect it to work, since the AI files should not be called on except during the turn generation. But don't quote me on that.
