What if every champ had 3 ability kits

What if champs had 3 different sets of abilities that players could choose during champ select to use on the rift some champs could even use pre-rework kits maybe tho I think it would take a lot of work to make over 100 characters that many abilities but it would be kinda awesome if riot felt like they could do it. It would kinda be like how MORTAL kombat V got it but on a league scale maybe ehh sounds complicated tho
