Sounds good. As long as they’re well made and with the realistic approach (no crazy stuff) I’d pick it up if the price was right.
The more types added from my list the bigger the chance that I’d buy it. 
For me it would be essential that each type had an attack from each side, preferably being able to be comboed together, one from above and one thrust/piercing attack.
A character controller might be overdoing it, most people will be putting them into their own character anyway and there is documentation on all that already.
I’d prefer more focus on having as many types of animations as possible instead. But what do I know.
