You'll want to post questions like these in the Historical Games subforums. Game Design is for people looking for feedback for rules they're working on.
That said, I can recommend
For King and Parliament, which is an ECW version of the To the Strongest! rules for ancients and medieval wargaming.
You can find a review
here. I also have a couple AARs
on my blog.
It's a grid based wargame, so that takes care of a lot of the little niggles of moving units, and since it's grid based, you can have differently based units on either side or even on the same side.
The game is played either with counters drawn from a bag or cup, or two decks of poker cards with the faces taken out (my preferred method). Cards are drawn to both activate units and fight. It's got an interesting "push your luck" method of command. Most units activate on a 2+ to start (so any card). But then you can keep drawing cards to activate a unit, but when you fail to draw a higher card (with modifiers), the whole brigade stops activating.
