Is it possible for a companion creature to take racial feats from a PC race?

[Pennate]

I've been wondering if it would possible to build a character that forms a self-contained coven independent of other PCs and NPCs. From what I can tell, the most effective way to achieve this goal would be to pick up multiple companions and give each the Coven-Touched feat, then take the form a changeling coven. However, the only way to give a companion a racial feat that I could find would be to build a Half-Orc Unchained Summoner with an Ancestor Eidolon; while the Ancestor subtype prohibits the eidolon from taking feats from its Summoner's race, the eidolon would also share the Orc Blood racial trait, which should technically allow it and the Summoner to take Racial Heritage (Changeling) and access Coven-Touched. I would prefer a solution that doesn't require borderline-abusive rules interpretations, though, and this still leaves the coven short one member. Is there any better, more widely applicable way to put a PC race's feats on a companion?

I don't think the exact thing you want is possible. However, there are means of gaining a cohort/followers who might be changelings - the leadership feat is the simplest, others are archetypes (tho' not of summoner).

It's easy enough to pass along teamwork feats, combat feats and even crafting feats to a companion without the companion having to meet the pre-reqs. But general feats I'm not sure.

A spiritualist's phantom might be able to pick up the Coven-Touched feat directly (I'm not sure if they count as the race they look like) but you'd still have the problem of being 1 member short and they specifically refuse to work with eidolons so it's not like you could multi-class with summoner to do both.

There is always the Leadership feat and similar feats that specifically grant humanoid companions. Yes, I know technically they are NPCs but for the most part you decide what they get up to and they are loyal to you.
