If there are any more people willing to create decent models, I'm all for it ;)
If anything is needed in Max, I can edit the in-game models a bit. But, you'll have to insert them into the game.
By the way, are you deliberately keeping all the heroes uniform? For example, the Elves have a hero (I don't remember the name) who would look great with the attack animation of a human knight. The Demons have heroes who would look good on a Nightmare, with the animations of a Necromancer. And so on.
