Well, let's see how they mesh:
- Luke uses Form V. It uses broad swings, and relies on aggression.
- Mace Windu uses Form VII. It relies on sudden, unconnected moves, which range from the subtle to the bizarrely wide ranged.
- Malak strikes me as a Form V user, with some Sokan and Ataru mixed in. Also, his great lightsaber is four feet long, altering his style some.
- I have reconsidered Revan's style(s). For one thing, he defeated Malak. He studied about other Sith lords, including Tulak Hord, whom I suspect was heavy on Makashi. Now, in the prelude to KOTOR, he goes into a defensive stance that mirrors Mace's own defensive stance in the Episode III game. Seeing as Nick Gillard, the creator of the SW forms as we know it did work on the game, it is a reasonable assumption to say that Revan knows Juyo, and possibly Makashi. He is also well versed in dual wielding.
