Any chance of changing Hero class?

maybe once you buy a hero class, when you respec you get the next hero free or something if that is possible? cause if you pick the wrong one or change your mind you have to pay around 900k just to change some stats which is pretty damn expensive, maybe keep the respec money the same if you change troop type, e.g. warden to zweihander whereas zweihander to royal guard could be a lot cheaper as it is the same troop type?
