I think this is pretty unviable. Considering that in Summoner's Rift where a single kill means much more than a single kill in ARAM. It essentially means that the people ahead outside of the laning phase dominates the sight problem since as with Altars it means that if someone tries to control the towers they make themselves vulrenable. Since sight is much more useful on Summoner's Rift there are likely to be teamfights. The people who dominate those teamfights dominate the vision and get ahead in gold and levels leading to a cycle in which they constantly dominate teamfights.

Even if you add items that perhaps make you invisible while capturing points (which wouldn't be counterable) or items that deny tower sight (which lets you know that the enemy is capturing those towers). That basically makes supports an sight item dispenser which personally isn't that good of an alternative. The current system to me is just more easier and simpler.
