Crossover Casefics and Post-Season 11

[jpgr]

As the subject says, I'm looking for Casefics. Multi-chapter preferred but they don't have to be epic. Post season fics can concentrate on either aspect of the cliffhanger. Also, gen preferred, only canon pairings.

I know I'm not giving many details, but...

The crossovers?

Houdini and Doyle (it can be done somehow)
Castle
Flash
Super girl
NCIS (original or NOLA)
Arrow
Criminal Minds
Bones
Grimm
Elementary
Doctor Who
Psych
White Color
Stargate (SG1 or Atlantis)
Chuck
Dark Angel
Harry Potter

Or anything else you think is *really* good
