You can trim the crap out of it so it fits, but parts will still be out of proportion and he'll eventually want to upgrade it all to a smaller ANH sized set. I'd recommend AP as a start. Else I think you can make it work, but will want to replace the belt/chest/back.
No matter what, that bucket has to go. At least, I'd never approve it as-is as GML with such a disproportionate lid.
