Modding

I apologize for the off-topic question, but I don't want to create a separate thread for just a couple of posts. I need to choose one main hero for each faction to lead the troops in battle.
Currently, I have chosen:
1) Isabel for Humans
2) Orlando for Demons
3) Markel for Undead
4) Fayden for Elves
5) Raelegh for Tower
6) Zehir for Wizards
7) Wulftstan for Dwarves

I haven't completed the entire campaign yet, so I want to know how successful my choices are. Also, I need to choose one (or two) heroes for each sub-faction (for example, Godric for the Griffin Empire and Laslo for the Holy Isabel Empire, or Biara for the Upper level of Inferno and someone for the Lower level). Ideally, they should have their own models. Thank you!
