HOMM4: is it possible to change hero appearance through memory editting?

[reko35]

I see mods change hero appearance to creatures, but sometimes with unexpected results. Can I do it with memory editting?
I learned to edit attack, defense, speed, skills, avatar and hero races. What I failed to find includes model and gender.
There are special campaign hero models so I think there should be an addess for it. Does anyone know its position?
