If she could have, she would have done so already with Katana.
I don't think Yoru has associated with "outdated" weapon devils in hundreds of years.
Bomb is obviously something that was already aligned with Gun Devil even in P1, and Barem could also count as a flamethrower man. The rest probably not.

They did imply in p1 that Gun and Bomb are associates (even if Reze and Gun really weren't).
However it might not be possible for Yoru to "own" a hybrid in the same way as a weapon devil, since Bomb technically belongs to Reze now.
