Yeah, in IX magic is much more intrinsic. It's in the blood, like a gift. The only magic that is rooted in an actual object are the summons; they come from different stones, but everything else is within each character. That's why only Viv can do black magic, only Amarant can do Chakra skills, and so on.
You could make summon stones, though, since Kuja was after those. Or, you could make the giant eye of his airship, the one that hypnotized summons (like Bahamut). That'd be pretty cool, heh
