Yeah, if one of those intersecting Horizontal/Vertical graphs would capture the data best...theoretically, you could post it in a thread like this and solicit comments for additions or changes...updating as necessary. But, is that the kind of diagram that would work best...maybe one of those circle-type things (a Bendiagram?) would be better. I don't know. I'm thinking you'd have to maybe create a compatibility graph for each character :(
