Hi EmiGeVe05, it is vanilla/definitive compatible only as far as I know. I've never tested it with Darth's mod, but I'm under the impression we modded a lot of the same aspects of the original game (AI, units, morale, battles, etc.), just in different ways. His is more of a sweeping enhancement of the game while mine is strictly a historical immersion project. I'd encourage you to try both!
