Shaco model rework

so for a long time ive played this game since i was 14,going on 21 right now. And ive notice some very particular differences to my champion main which is shaco ive noticed his color scheme where he is on the splash art red and brown but in game hes orange and black or a dark blue,i wanted some info as to why he still has his same design from back then im not asking,"hey rework this champion because hes my main" not asking that at all but more of a queestion as to why his model hasnt been changed yet or if there is gonna be a model change later in the future something that matches his base splash art,id love to know and if it would be possible not any time soon but some day he get his model updated a bit
