Suggestions to aid League of Legends

Hello, i just wanted to give out a suggestion to riot about League of Legends Towers Specifically the ones residing in Summoners rift. For the most part the towers are EXACTLY identical! My question is why ? It seems like a great place to show off some cool art designs from the community for towers and possibly help mix up the game.

My idea is this! As towers get stronger depending on each tier, make them look bigger, or make them more menacing in appearance (more armor/bigger pew pew beam) As for T1 towers, you can have it look simple, and cleaner. T2 towers have shields so it would make more sense to have bigger shield than the rest, etc.

That's all i have for now but I hope someone can reach an employee on this and share the new!
