Could we re-skin pre-existing models? Maybe use a Carth model, Jolee model or Darth Malak model, for example, and slap some paint on them? Or maybe just use a generic Dark Jedi model, if re-skinning is just too dificult.
Either way if you are interested in maybe trying this out I would very much like to help with choosing stats, powers, and items for the various combatants. I think the main idea would be to make them as true to character as possible and reflect their strengths and skills accurately. Perhaps even have a circuit of progression with the combatants getting stronger and stronger till the most powerfull one is finally battled.
Just some thoughts about what could be involved, as I shared before I've been pining over this idea for years.
