The con job is a classic story plot. And it's perfect for a roleplaying game scenario too.
So. Many. Things that could possibly go wrong!

Who are you and what have you done with Ben? Have you been talking with Jim too much lately? This sounds like one of his ideas! Are we sure Ben doesn't need psychiatric treatment for a broken brain instead?
Anyway, it rather seems like BB-8's come to get the other characters moving again. I really doubt the psychiatrist plan is going to be used as that's not a Star-Wars-like thing. Cut to the shuttle for a change of plans scene perhaps? This balcony has some nice architecture, but it lacks for privacy, and for a place to gear up.
BB-8: Guys, there are rich aliens in here literally giving money away!
BB-8: I got a whole bunch of coins. Is it enough for our First Order plan?
GM: Not nearly enough yet, no.
Rose: We’re still gonna have to clean the place out. Finn, what security have you spotted?
Finn: Nothing yet. It’s well hidden.
Rose: Change of plan! We pull a con job!
BB-8: Uh... What do you propose?
Rose: Find the richest person in there and give them a sob story about Finn being a veteran in need of psychiatric treatment.
Rose: I’ll play the psychiatrist and charm them with my magnetism and justifiable need for up-front payment.
Finn: Buh... buh... uh... whaaa??
Rose: Good! Getting into your role already!
