This might not be what you wanted, but you could always test this. It won't take many resources - just see if people get confused if the categories' contents are not mutually exclusive, or if they get lost trying to navigate around. In some cases, my guess would be that it's okay to have some items at different levels, but on others it would not. This could be a tricky one that needs each item considered individually if you want to get it spot on.
It might even be worthwhile running a card sort on the sub-categories to get the best idea of which super-categories they fit into (I'm assuming you haven't already - apologies if you have). It's a quick and easy (ie, quick and fast) test to run. Card sort results should be enough evidence to show how other people (ie, customers) might categorise items and be close enough to get the job done quickly. Apologies if this isn't what you wanted. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
