Pathfinder 1E OGC grafts and symbiont subtype for Pathfinder?

[VelvetViolet]

I'm trying to find an open game content replacement for the grafts and symbiont subtype from Fiend Folio/Eberron that's designed for Pathfinder. Are there any books that have this?

EDIT: As far as I can tell, Chaositech and Radiance Players Guide have graft-like mechanics released as open game content.

EDIT: Legacy of the Dragons has vallorian living weapons/armor as a property that can be applied to equipment, with a web enhancement available on Monte Cook's site (only accessible though the internet archive after he gave his site a makeover and removed all the old content).

EDIT: The PF products Primal Host and Fleshwraith apparently have graft or symbiont-like mechanics.
