Sightstone build path QoL?

What if, instead of Sightstone building out of + 400g, it built out of + + 325g? I would think this would be a small buff just because there is not as much pressure to build Sightstone immediately, and if things go wrong in lane, you could get just the crystal and a couple wards and be good until you can get another 825g (so you can also upgrade gp10 item). And if, for some reason, you end up not using all the wards you buy, you can just build one into your Sightstone.

Any thoughts?
