D&D 5E Kobold press Deep Magic and Sorcerers

[Tales and Chronicles]

I was reading through Kobold Press Deep Magics yesterday and I had an idea for an upcoming game. Sorcerer's small number of known spell and shared spells list are always discuted when people talk about the class. I had the idea to allow my players to gain access to a specific Deep Magic when choosing their origin, letting them have thematic spells fitting their arcane blood. They would still count as spells known, not free spells, but I think it would allow sorcerers to have a special flavour.

Chaos Sorcerer-» Deep Magic: Chaos Magic
Dragon Origin-» Deep Magic: Dragon Magic (not yet on the store)
Storm Sorcery-» Deep Magic: Elemental Magic (coming soon)
UA Shadow Origin-» Deep Magic: Shadow Magic
UA Favored Soul-» Deep Magic: Angelic Seals

Has anyone tried this, or uses those documents in their game?
