Yes. She can control Mario, so I don't see why she wouldn't be able to use it in a fight against Goku. I think Motion Cancellation is in character too, but it's only temporary, so it couldn't really do too much. Rosalina's possession is a huge advantage that she could use to take control of and kill Goku, but Goku has quite a few other advantages as mentioned above (and he should also be at a decently high end of Low 2-C, so my final vote is Inconclusive.
