Better upgrade for supports with sightstone.

So I was reading a thread on reign of gaming the other day, and it was talking about the amount of gold supports get the more assists they have. Someone else mentioned maybe instead of getting more gold, it went into an item or something. That got me thinking, what if (I know it sounds kind of crazy), you had the option to "sacrifice" your trinket, and merge it with the sighstone. Basically, it would give the sightstone and extra property, making it similar to rengar's bone tooth necklace. Every certain amount of assists, you would get small bonuses that would be beneficial to supports (so it doesn't get abused by other roles). To make sure this doesn't get abused by sigh stone junglers, that's where the idea of merging your trinket with the sightstone comes in. You to make the decision of whether these new stats would be worth giving up your oracles or warding totem. I don't really have any ideas on what kind of stats would be added, but it wouldn't be anything too major. Maybe some mana regen, small amount of ap/health/armor/mr, or it would increase the vision radius of your wards (like the mastery), give you some sort of move speed boost, or give you a cd reduction on your activateable items. It wouldn't necessarily have all of these, just tossing out some ideas. If anyone has any ideas about this, I'd love to hear them!
