I'm just being realistic. I want Scorpion in too(not as much as some others). The thing is, MK characters don't even do that many aerial moves. It's not exactly hard to fill out the attacks as is.
For that matter, what makes the Spear different from the Hookshot? The idea it has to be bloody violence when it's just a feature of the MK games, not necessarily how they're represented otherwise. Even then, there's many MK games which have a No Blood option, including some Nintendo ones. It's quite doable. In the case of Scorpion, he has had weapons throughout the years. He's has swords, axes, and the usage of his spear like a kunai alone. It's not all that hard to make a pleasing moveset. His Aerials could simply consist of a forward overhead punch[Forward Air](similar to Ganondorf's, Mario's, and Dr. Mario's), his usual aerial kick that many characters had in the past[Neutral Air], and then you have things like swinging his sword upwards in an arc(not unlike what a lot of Fire Emblem characters do)[Up Air], a simple backhanded punch[Back Air] which could be a reversal of his Teleport Punch. So that leaves a Down Air. One option is using his Spear as a Meteor Smash, which would have low range but be extremely effective in its knockback in return.
Another important thing lately is the Combo Breaker. Though that could be his Throw button while used in the air, especially if his Up B is a variant of his Teleport Punch(and that punch could be more similar to the Cyber Ninjas). It ultimately depends upon how you go through the Specials, as he has a lot of abilities. Though his Down B could be a counter version of his Teleport Punch instead, which would basically be similar to Lucario's Counter, but he'd teleport around instead of simply creating a double team.
And that's just one of many characters. All kinds of MK characters have way different moves. You could use a similar mold for a counter move for different ones. Like Sub-Zero's ice clone to freeze someone temporarily instead.
