I still think covers this. It used to be recommended on Soraka because of her ease of assists - back before play-not-to-lose meta (aka, passive). The upcoming Plate of the Warmage (leaked in the PBE) is AP/Armor item that stacks up on unit kills (like Bloodthirster) - perfect for a support (AP and AD-defence) except for the small issues of "unit kills".

Unless you specifically mean being able to obtain stacks without having to do anything (like Thresh can collect souls without needing to be involved).

Maybe add the following aura/passive to Philosopher's Stone: "Whenever a nearby allied champion scores bounty, you gain 2 gold." (So the support version of Avarice). Or: "Whenever a nearby enemy minion dies, there is a 20% chance it'll drop harvestable loot. Loot is worth 10 gold." Loot can only be collected by people who hold Philosopher's Stone and won't drop unless someone near has Philosopher's Stone. You might say it's overpowered in the jungle, but except on Nautilus, Maokai and Sejuani (and any other "support junglers"), I don't think Philosopher's Stone competes with Sightstone as far as prospective build paths - especially for only 20% chance.
