It's still left to speculation on how he is able to have two DF abilities. Marco said he has a special body, but we've got no idea what that means.

As for your idea DSP, it doesn't really explain much since the way DF powers can transfer from a fruit into a body or from a body into a fruit, it'd be the same if you transfer the DF powers from a body into a weapon or from a fruit into a weapon.
