I think the Miami GB was just awkwardly timed. It seemed like there were 10 other sales going on that were better, that I spent my money on. Although now I can't remember what they were exactly. But if somebody revived it now, maybe it would be more popular, or people would have more money to spend on it. (IIRC the problem was people ordered and bailed out or something).
As for moogle kits, somebody is always looking for one. Because nobody ever thinks they're going to need a moogle kit, until they need a moogle kit.
