You'll have to cut down the back of the ANH Luke neck and squeeze it in and reglue it back together so it's less wide and will fit the RM Alex sculpt as the way the body comes stock, the neck is too wide to fit the sculpt.
The inside of the RM sculpt will also need to be drilled out so it sits lower on the modded neck.
Grateful for the excellent tips, cheers friend! :duff
