But M&H and Xet are very different. M&F are just making inventions and having fun while Xet is evil and trying to take over the world. Sye and Caren wouldn't make much of a team.

The only real way they could team up if Midas and Herb were trying to take over the world itself. However, since it seems Xet is tricking them, Sye could just be trying to warn them, which isn't what Caren would want, since she wants the three to keep on doing what they are so she can show her parents. Sye doesn't because if Midas & Herb are doing the same thing Xet is, it'll be deemed noemal and Xet won't be considered an alien.
