Your reasoning seems to be from the perspective of reaction to an attack e.g. one character  punches another character transfers a force upon that character which moves him and when doing that the appropriate frames of some animation will render. This makes perfect sense and is definetly an interesting solution to try out. 

However I'm more concerned with movement of the character that is throwing the punch, because the punch may be extra ordinary and in order to look good the character needs to be translated in a precise and non-linear fashion. When this is the case, the force based move is really hard to get exact enough because of it's smooth nature. 

The only solution I can see to this is to either not allow this kind of movement or doing it by predefined translation, in which case I seem to be loosing physics support for the character. But maybe the implicit integration method could be good for this...as you said it would be good to find out so I guess I have my next home project all layed out before me:)

Oh don't get me wrong it's pricey but rightfully so, I haven't worked with it but it seems to be a remarkable product.
