Why not just have Name-omancy be your Channeling/Ritual? The only restriction is you can't do a spell you don't have a name for? For example, everyone knows that fire's name is Brisignr, so fireballs are common. However, not many know that wind's name is Austru, so flight is a lot less common.
If you like, change the Refinement rules for channeling/ritual if you want to be able to pick up specialization boni.
Remember, since the magic is in the name, you need to speak the name to invoke the power. This means no such thing as silent casting. Also, any focused items must be carved with the true name of whatever it aids with.
Just my 2c.
