Well that was just a joke design they made for the show, they never intended to keep it. It was a nice joke though.
You do realize they can make iconic looking designs and split them into gear pieces, right? They can get the classic skins and split them. Just because they split skins that should be made of of the splited pieces doesn't mean they are gonna make completely original skins out of them. Harley Quinn in IJ2 for example got a skin that is very resemble to her classic Batman cartoon skin out of gear pieces that you needed to unlock, so they can do the same thing for MK11, and perhaps make skins the fully resemble the originals.
Also for skins in MKX, yes Scorpion and Sub-Zero got more skins then anyone else, but Kitana, Liu Kang and Johnny Cage also got a good amount of skins, and all of the other non DLC chars got between 3-5 skins, and a good amount of the skins was for classic ones like the UMK3 male Ninjas, MK2 female Ninjas etc; and also Quan's MK4 skin, which was good considering that he got the same default MKDA skin all the way until MK9. Even his head and face structure across all of his skins, if you noticed, was the more realistic one he had in MK4, and not the less realistic one he had from MKDA until MK9.
