A perhaps-relevant quote from the aforementioned Tardis talk:Canon policy/Archive 2: CzechOut wrote: The only sane policy for determining valid sources is one firmly based on out-of-universe considerations only. (emphasis his)

In other words, as long as a story is (1) properly licensed and (2) non-parodic, it shouldn't matter what characters are in it, even if they originate from Dimensions in Time, Star Trek: The Next Generation, or any other invalid story. This is a clear and consistent application of the rules as they currently exist.
