The "Island of Mages" mod replaces the heroes with BF units.

You know, try creating new heroes and taking specialists from the NHF mod; it will make the game more interesting. I'll try to take a look and make it so the mod doesn't change anything but adds heroes. There will be an update, so let me know. And improve the hero animations; some of them are lagging behind and then catch up. If my vision gets better. I came up with an idea: I'll put the heroes into the NHF and see what happens; maybe I'll laugh.
