I think the biggest problem with Sagume is... Yeah, Lunarians. Though the overarching incident would in theory get them involved, I'm not sure if Sagume would have any reason to intervene herself considering what she has to handle up there on the Moon in the first place. Also, her ability can get jank in a way that Remi's can't, so yeah.

Other two should be fine, though.

I'll make an OoC in a bit.
