You can do exactly that with the larger version! you set up animation entries on a per character basis. Each entry is a sequence of FX, movements. sounds, or nested sequences. each entry can be connected to a keystroke. When you target a toon it loads his/her animations and binds it to keystrokes in real time.
As you are building you can preview the animations in game. The larger version comes with a UI database to make this effort relatively painless.
Highly recommend you check it out as I think it does everything you need and a bunch more!
