No, it doesn't. Unless they initiated one more recently. If so, please post link
There was even a time not too long ago where cross overs were not only overly-abundant, but were heavily advertised up the wazoo. That so Suite Life of Hannah Montanna, Wizard's on Deck... Shit, even Lilo and Stitch had three different cross overs going in their one series; Proud Family, Kim Possible, and Recess.
Was Recess even still being produced at that time? If not then I have hope a canceled series can return for crossovers.
