I don't think the cheap castles are overpowered so much as the more expensive ones underpowered. I think a good solution would be to give special bonus to each of the less used castles. Dark Citadel could spawn skeletons, normal Citadel could recruit two commanders per turn, Fortified City could draw population from other provinces, ect..

That is a good suggestion, although I wonder why population draining is a good thing. Maybe an additional growth bonus would also do...
