Luffy hasn't done that yet. We don't know for sure that he will. We don't know if G2 and Koka used together are actually what caused Red hawk. We don't know if it would do this when it's his whole body anyway. Hell, we don't even know if this hypothetical technique would work the same as hell memories.

and your saying Oda's being unnoriginal because of something he could pottentially do, when there's no reason to assume he will?

Really, what you mean is, you had an idea for Luffy, then realised Oda had already done it. Don't take it out on the author, that's just being unreasonable.
