Well, I'll take my L. Yamato for nakama makes absolute sense to me, however, I don't rule out the possibility of Oda changing his mind and leaving the crew as is
1) Go through with the Yamato stuff and make her join (most likely option imo)
2) Pull a Jimbe and make her join later
3) Do something completely different and nobody joins this arc aside from Jimbe
I think I'd be severely disappointed if she didn't join, but honestly I'd take the L and move on, something Carrotbros and Tamabros don't seem to be able to do in the least
