Balancing shouldn't be too hard 2bh each tier gets a selection of arms and armor to choose from and a set amount of skillpoints etc.I remember the custom knight orders in the Prophesy of Pendor mod. While not the same as a troop tree, it was fun working to create my own units and training their skills until they became OP as hell. I am all for this idea, but there would certainly need to be some balancing aspects to them such as making sure lower tiers cannot use too powerful of weapons/armor, etc. It could be a great money sink too, because in late game you have far more money that you ever need.
Could also have a choose what you want and be balanced by cost/wages.
I like the idea of making a small but elite group of royal guards or something along those lines.
