I love what Riot did with jungling, especially smite diversity. What if exhaust was like that?

We already have "supporting items". What's stopping us from allowing exhaust to be diverse, in the sense of choosing what it does based off your support items? Very few champions outside supports take exhaust anyway. No one outside supports takes the three gold-income items. It seems like an easy match. That could also lead to more diversity with the gold income items in the support role. For instance, what if you could start the Ancient Coin, then build it into the Frost Queen's Claim by grouping phase? Granted, the stats of the items would have to be correspondent to which items you start out with and what it's built into to keep the game balanced.

Could this work? What are some ways we could use these items to alter what exhaust does to the enemies and for our teammates? Pipe in guys. I'm legit curious about what y'all think about this.
