Supernatural Story Finders

I have come to be a bit addicted to Supernatural crossovers and have been craving some completely awesome fics where the boys and the supernatural trip into other shows, especially the (semi)procedural cops-like shows. I've been able to find crossovers with NCIS, Criminal Minds, Numb3rs, Medium, Leverage, Dark Angel, Psych, Bones, ect, but I'm having terrible luck finding crossovers with these awesome shows!
-The Mentalist
-Hawaii 5-0
-Castle
-Suits
-Haven
-Eureka
-NCIS: Los Angeles
-Rizzoli & Isles
I would be super grateful if anyone could find SPN crossovers with any these shows. Gen or Wincest is preferred (or very minor-barely there het), long or short is awesome, and self-recs are welcome.
