If you guys still plan to do this, it's 100% possible pretty much now.
6 letter long names now work 100% so that cuts that out of the problem.
New Techs aren't that hard, she seems to be magically orientated with all elements, so pick a few from there and maybe recreate a monster tech for her.
New Equipment...Only problem I see are the weapons.
Sprite Assembly, not much SA is needed really. Maybe a few things but not that bad actually.
Status Screen Picture, I have one that just needs to be recolored and whatnot if you guys need it.
Attack Sound Effects, I suspect her using a dagger or magic. If you go with magic, make a very weak tech that can only be used by her and only her for attack. Change the attack bytes to that of the tech, there you go.
It shouldn't be too hard to get it, just the sprites would need to be made.
