What you are talking about is already there. Each AC: Slash, Pierce, Blunt, and Magic would only put some resistance to that specific kind of attack. Using a firey sword on a felar would still hurt the hell of out of the felar. But, in any case, it's not really important since as Nepenthe said, it would be far too much work for the rewards. I am surprised people are focusing on this and not my empowerment idea. The empowerment idea I thought was really more beneficial to the CF community and much easier to implement, but no one really seems interested in it.
