Minions based champion idea (From Despicable Me, not the lane minions)

So i'm not a game designer and I'm awful with concept art on the computer but here's a fun idea for a support AP champion. Make a champion that's 3 little yellow guys with funny voices and full of utilities. You can have each one of the 3 have different abilities, use q w e to rotate between them and have R to combine them. The passive could be something utility based as well. I think this could be a really fun champion to design.

Again, I know nothing about game design. So far the concept seems a little similar to Sona's different chords. I literally thought of this 5 minutes ago, but its definitely a fun creative take and I know Riot loves taking fun ideas and concepts from existing characters and building new ones from them. You could do better to make them yordles instead of minions.

They could even have fun taunts and stuff like stacking on top of each other to try and look more scary then falling over or a synced up dance.
