Man, that is one phat G string there!
Seriously, this "upside down" approach
must affect your whole playing in a way that you should sound like pretty much no one else! I remember a Michael Schenker interview where he raved about the UFO-/MSG-rhythm guitarist/keyboardsmith Paul Raymond who strums a Non Rev Firebird like that (i.e. strings "righty", but played "lefty") saying that "everything that Paul plays sounds a little different because of him having the strings in the "wrong" sequence, I am always searching for that sound".
