I would go with the idea of the evil wizard moving between every 3 heroes myself, if you were going
to change when the evil wizard moves.
Otherwise...just make sure you have enough copies of all the spells, and I would certainly add new hero types/classes,
not only to keep things different, but to give everyone the chance to be in the spotlight.
And you will, of course, want to add monsters or beef things up a bit. This thread offers a very clear and concise talk
on my idea of how to balance things out nicely.

on the inn so far. Set number 1 is the most extensive...and I might suggest that one if you want to include more spells
and a "priest" type character. Also - check out my expanded monsters, hero spells, and evil wizard spells here:
