In this case, it would be somewhat problematic for Vivio to suddenly start attending a school on Earth. Vivio's not likely to leave Mid-Childa unless Fate and Nanoha are both gone on a long-term assignment. Assuming that said assignment (let's assume the TSAB has taken an interest in Pharaoh 90's activities) takes them to Earth (which makes a certain amount of sense, since Nanoha knows the territory pretty well), Vivio would probably be attending a school in Uminari City, not in Tokyo.
Still, you have a point; the presence of the multiverse in Nanoha makes crossovers easy to pull off. Good crossovers, on the other hand, now that's a different story entirely.
We my idea was along the lines that Vivio is having problems in Mid-Childa schools because someone found out she is what she is, or for some reason people can just sense something different about her. Also i think that one day Nanoha and Fate might finish their terms of duty, maybe Nanoha might open up an expansion shop somewhere.
Other ideas, Pluto wondering where this Girl came from, she has no past. Vivio and Hotaru's location being attacked by a monster of some type, and Vivio emulating Nanoha-mama, and atomizing the beast, before Hotaru can fully duck away to henshin...
Few other random ideas but it is sleep time.
