Well right now it is impossible to upgrade them, the same being with the Bulgarians. Right now the only way is to release prisoners to join thy. But since it is an issue you point out, I think we must do something for that. For example the Portugese Serf which is a mercenary has an upgrade troop tree, but the pointed bandits don't.
I will look upon it in the next version. Thank'ya
