Tower Taking/Defending Team Concept?

Just a thought on an idea I had a few days ago. If anyone has a party of 5 or can somehow make this work with randoms please let me know.

A giant part about winning games is the ability to hold towers and take them. Out of curiosity, I came up with a team comp that might work.

ADC mid/supp mid/supp/top top/mid and a tank with heavy CC. Maybe jg.

My concept for this was to take and protect lanes. Trist and Ziggs have an amazing ability to take towers using abilities while Azir and Heimer have a great way to hold lanes. Some for of tank is needed because it is a squishy team but the reason I mention Sion is because of his engage and heavy CC. Naut would work too.

I do see some downsides to this team comp however. Most of them are squishy, don't have too much to offer as far as CC goes, and it is rather AP heavy. So facing a team that can stack CC is rather unfortunate. But what they lack in CC they make up for in snowballing such as Ziggs, Heimer, and Azir.

If you have any thoughts on how well this would/wouldn't work feel free to comment or even change up the team comp. I'm interested to see what you have to say.
