Dark Knowledge equivalent as a feat?

[Trekkin]

On the homebrew boards, I'm attempting to create a psionic archivist, but is it possible to do the reverse: is it possible to take the best of an archivist's applied knowledge and add it to another class?

I am aware of the Knowledge Devotion feat, but are there any more feats or abilities in its vein that provide a mechanical bonus from a Knowledge check?

Ritual Blessing or Ritual Blood Bonds if you're a Half-Orc, but both suck and were bad ideas for feats. similar ideas were later used to better effect in 4e as Rituals
