I'll have to check, but I think Bespin Luke's arm detaches in a different way. Hope I'm wrong as I'd love a light-up sabre for both figures.
Yeah, I think you might be right there, but not positive. Plus Bespin Luke head has a fixed neck sculpt and this Tatooine body has a fixed neck on the body so you could never use those two together. Probably need some custom work to swap out the arms or something.
This is a nice looking shot.
And the whole gang:
Still tons of detail:
