I do not believe Yamato is joining.
The main reason for this, is character design.
Yamato looks like Nami with horns.
When creating a main cast character, you need to make their design distinctive and easily distinguishable from the rest of the cast. Outside of her horns and height, Yamato is basically Nami 2.0, and that is why I don't think she's joining the crew.
