IDEAS for Ruby Sightstone (and perhaps Trinkets too)

Right now, Ruby Sightstone is useful for little more than extra HP. Here's 2 ideas to improve it that I haven't seen suggested elsewhere.

1. Upgrading to Ruby grants special interactions between Sightstone and Trinkets. For example, destroying wards using Sweeper or a Vision ward, or spotting enemies with Scrying Orb, could restore a ward charge.

2. Upgrading to Ruby enables Sightstone users to upgrade Stealth wards to Vision wards. Casting Sightstone like a targeted spell on top of a placed Stealth Ward upgrades it to a Vision ward, consuming 1-2 ward charges and counting towards the Sightstone holder's Vision ward limit.

What do you all think?
