I can help too!
Just for the record, I know two battle systems that can be put together, and a third possible one (hard to use but awesome)
Blizz ABS
Animated Battlers side view (default battle script, just handles graphics differently)
Gubi-Tactical battle system (possible. Haven't tried it with the above combination)
That's two battle systems, maybe three. all different in how they work
Um, i'm also a decent spriter and i'm a great eventer.
At the moment if I end up doing any sprite requests those may take awhile, I'm working for two guys already
