Okay, here's my hat in the ring. Leia is signed up for the mission, but if she doesn't get picked to do her diplomacy thing, she'll probably do some exploration and bring things back on Romeaus's list. She's roughed it before for long periods of time, and thanks to Luke's quick thinking, she has a pack ready for being out in the wild.

Kanji will either go out exploring or stay in the village. He's got nearly no camping experience. That one time with the school doesn't really count. But, well, he's a healthy teen with a lot of strength and power in his Persona. So, if anyone wants to drag him along with them, I'd be up for that too.
