New Game Mode Idea

I was thinking if riot could make a new game mode called Slots for the upcoming rotation queue. So, in the lobby, players choose a champ. That champ keeps its appearance, passive ability, stats, etc. The only catch is once all players have locked in, 4 random abilities are chosen. There would have to be a couple rules such as that the ability must coordinate with its type. For example, a champ can't have 4 ults or a w ability in a q slot. Additionally, all teammates can see their teammates randomly chosen abilities in the queue. Not only would this be super fun, but it would also promote teamwork and invite so many combos that league has never seen before! But to me, the most interesting part would be to see how players adapt to use their new move sets effectively. I thought this would be a cool idea. What do you guys think? Inform me if I made a mistake in the comments :p. THANKS FOR READING!!!
