You're forgetting the most important part! If you glamor a wand to a staff which swing speed would it look inaccurate if a wand swung as slow as a staff!? (or vice versa)

Anyway, with the FF13 weapons coming to Mogstation soon I should hope something like this is actually in the works. Would suck to buy the BLM or WHM weapon and have nothing to glamour it onto.
