Neutral heroes.

I have a new idea – neutral heroes; as far as I know, no one has suggested this before:cool:. So, let's say that almost the entire map is a forest, and a Necropolis hero is walking along a forest path. And on the road, there's a hero – an "unknown" one. And in battle, it turns out that this is an Inferno hero. Next, it could be Mages, and so on. Also, their army grows with the increase in creatures from their castle (but there are no neutral castles). And also, if there's a lot of money and diplomacy is well-developed, you can buy this hero. Troops will then keep coming to him in the way described above until the hero dies. What do you think?
