Frankie Edgar vs Jose Aldo in Lightweight , who wins?

Jose should move up in weight and fight in the UFC,he has nothing else to prove against the weak competition of the featherweight division in WEC,ok he is the best there we all know it,now he needs to man up and sign in UFC and lightweight,he is tall enough to be a lightweight , he is too skinny for a featherweight,i hope he is not another coward like Anderson Silva who will starve to death only to never face better competition in a more competitive division!
