Insane Difficulty: Ogre battle new sprites? - Insane Difficulty

Hello friends. I am a big fan of ogre battle and recently have found this site. My question is simple:

If i provide new sprites for new monsters and classes it would be too hard to implement it in game?

My idea was to convert the sprites from ogre battle 64 (cataphract, centurion, dragons, etc).

I would like to know if it is possible and if you people were willing to do it.

You can probably ask Zombero, who runs the Ogre Battle Hard Type hack.

I think he's changed the colors and sprites already.
