Perhaps as heroes. I haven't thought it all the way through for them, but I definitely want to add them in. They were given by the Valar, so I have thought about giving them to the Good Civs when Mordor achieve a certain amount of tech/power/evil points. I also want to add a corruption system similar to the one I am planning for the Ring - too much evil deeds will result in the Corruption of the Wizard. Saruman would only be given to Isengard and would be the easiest to corrupt, then the Blue wizards, then Radagast, and Gandalf would be very resistant to Corruption.
Yeah that sounds good. Having them as heroes would work. Saruman could give a science bonus. Gandalf maybe a combat bonus (or just be very fast moving), Radagast some sort of bonus for animal squares or healing bonus. There is so little written about the blue wizards that you have pretty much creative license to do as you wish with them!
