There are similar mods available online. They feature Orson as a dead peasant, and so on...
But I believe having heroes with "video crit" is a no-go.

I was thinking... People have the angel hero Linus. Maybe we should add a hero called "Faceless" for the Dark Elves? For example, Yorgen?

It's possible. We need to think about it.
The Fallen Knight will immediately give +5 to Dark Magic (Yorgen has +6 to Dark Magic and enhanced skills (level 7 and 6)). Since I'm adding a skill point to everyone, we can now give the "Fallen Knight" at the start. But the special ability itself should be based on education (and there's such a special ability for Sergio).
Then we need to find another special ability for Sergio.
