Hybrid characters should be interesting for their story, not their mechanics. I think some "Hybrid Feats" would be a potentially good idea, but making those orthonigical and optional to Hybrid status is better: you can have an Elf with no Feat who is of Orcih extraction, an elf with some "Orc Heritage" Feat, an Orc with no Feat, and an Orc with "Fey Ancestry" fest, an Elf with "Fey Ancestry" Feat or an Orc with "Orc Ancestry" Feat...and all 6 be siblings expressing differently.At the cost of disincentivizing mixed ancestry characters for everyone who cares about their mechanics, whether they're hardcore optimizers or not.
