Scorpion is most known for the spear pull but a lot of the characters in here already have a copy of that move. MK emphasizes on the brutal fatalities and they wouldn't work in this game. Supers have to be quick and not so violent. Scorpion with the spear that a lot of people already have and with no fatality=doesn't add anything to the game.
Which is why Sub-Zero makes a better addition to the game.
His freeze moves would not be very similar to Cole, and his ice clone mechanic would be totally unique as no other character in all-stars has that move. It would add a nice lure-and-trap mechanic to the game.
Definitely an MK rep. would be awesome, preferrably Scorpion, Sub-Zero or Shao Kahn.

They could obviously give Scorpion's spear different properties like being able to go full screen and stunning the enemy on contact for a second. (Have to be true to how the spear is in MK)
Scorpion is the better rep in my opinion. He has better potential for supers and a moveset that doesn't completely revolve around one thing. *Cough Sub-Zero ice attacks*
