I don't see why he shouldn't at least TRY a scalloped neck. Its kind of like the 7 string issue. People say, don't try a 7 string guitar until you've mastered a 6 string. But Rusty Cooley makes the good point that you can NEVER master a 6 string. You'd might as well do all that you can so that you can play how you want.
Give it a try, all you need is a file and some sand paper (and probably some linseed oil too). Buy a cheap used guitar and give it a try.
