If it's basically like Alteration but permanent, what's the downside ?

This school would be awfully powerful for SCs, no need to split research. Blood works this way, too, but Blood has a lot of hindrances.

I'm not directly against this idea, but I'd rather see some schools/paths made more viable. Water magic comes to mind.
I think Water magic should simply get more spells*, to compensate for the fact that at any time you have roughly half as much spells available. (water/underwater)

* and more variety. Underwater spells would feel unique... but the impression is dulled by low number of spells.
