|That Crazy Alchemist|
As someone who hates the existence of Eldritch Heritage for basically giving any class the most defining feature of another class, I can't say I much like the idea of this since it just does the same thing to another class. I mean, why stop there, why not have a feat that grants Spell Schools, or one that gives Sneak Attack Progression, or Bomb progression, Lay on Hands, or Wildshape. Why even have classes when we can just give any class another classes best features for the price of a feat or three. But I digress...
As for balance, I'd say this is quite a bit stronger than Eldritch Bloodline. With Eldritch Bloodline, you start at the lowest rung and have to work your way up the feat chain to get the best stuff, regardless of your level. With your feats they can just go straight for the best goodies from the Oracle with the very first feat, as long as they meet the level requirement.
To balance this, I would put a cap on the level requirement of the revelation you can pick for each one.
So the first one might say "you may only choose a Revelation that a 1st level Oracle could choose"
The next one might be for 7th level, the next one for 11th or whatever. Make them have to climb the ladder, don't let them start at the top.
