Not by much if you want me to be blunt with you. Doesn’t change the fact that it requires an unnecessary amount of time and programming just for “paying an homage”
This post explains my point best just replace ender with shadow move.
Plus there it also brings issues as far as utility goes. You put examples of characters that have similar looking shadow moves, but does everybody have them? What can moves can he take from characters like TJ, Hisako, or Kan-Ra (each with varying degrees of speed and number of hits) without it looking weird?
Now could I see this returning as an ultimate? Maybe. But as a main part of his toolkit? No.
