Criminal Minds Crossovers

Defect (http://www.fanfic.otherplaces.net/defect.htm), the BAU catch up with Dean before his deal becomes due. An AU ending for season 2.
Followed by Hell and Back (http://www.fanfic.otherplaces.net/hell.htm) and The Hunt (http://www.fanfic.otherplaces.net/page80.html)

The Time has Come series (http://jujuberry136.livejournal.com/tag/timehascomeseries). Sam and Dean tangle with the BAU to resolve a case. There are two sequels, all can be found at this link.

Sour Cherry Pie Life (http://faithburke.livejournal.com/50588.html) Dean has retired to the civilian life. Too bad no one told the serial killer currently stalking teenagers in Indiana.

Fanning the Flames (http://mandraco.livejournal.com/21960.html) Someone or something is going after fans of the Supernatural books. The BAU think it's a religious nut. Dean and Sam think it might be a restless spirit. Only one team is right.

Fangirls, Unsubs and Classic Cars (http://www.fanfiction.net/s/8446945/1/Fangirls-UnSubs-and-Classic-Cars) Prentiss and JJ are hooked on the Supernatural books by Carver Edlund. Then they encounter two brothers who drive a '67 Impala....

On Our Own Terms (http://jennytork.livejournal.com/624198.html) -- SUMMARY: This was not a fixed point.

This could be set to rights.

This was what went through the mind of a lone ranger Time Lord when he found himself unexpectedly face to face with a teenaged human boy with demon blood.

Pre-series for SPN, AU for both series

I know you haven't listed NCIS as one of your fandoms but maybe you want to give this one a try. One of the best crossovers ever:
When Worlds Collide (http://www.fanfiction.net/s/9018850/1/When-Worlds-Collide) by elfinblue
Summary: When a kidnapped Tony DiNozzo is rescued by legendary - and supposedly dead - serial killers Dean and Sam Winchester, the NCIS team takes over the Winchester investigation. What they find is a file filled with contradictions and impossibilities.

Had to tell you I loved this one!

Criminal minds one, Hilarious and quite believable after Demonology.

Absolutely loved "Eat it, Twilight" http://liliaeth.livejournal.com/343958.html -- Criminal Mind's crossover with dead teenage-girls and a pretty good suspect named Dean Winchester.

I adore this Dr Who fic, but I must warn you it is Dean/Donna (no sex scenes though)

Doctor Who Universe crossovers:
Apocalypse Soon by gladdecease
In which Martha Jones and the Doctor tangentially involve themselves in the Winchester's apocalypse by helping Castiel heal and get back to their side after carving angel-repelling sigils into his chest.

Supernatural crossover collection - of Doom! by gladdecease
Self explanatory title is very self explanatory. Follows ye olde traditional five-and-one format, in which five is "reasonable crossovers" and one is "where the hell did that one come from?" (chapter 2 is the Torchwood crossover)

The Angels Have the Phone Box by gladdecease
It's his TARDIS, not a free-for-all time machine. But since they ask nicely, he lets them borrow it.

Ricochet by brodylover
The Doctor [11], a hopeless romantic, goes to Purgatory in order to find Castiel and drag him back to the plain of the living, so he and Dean can finally talk through their feelings.

and then shall that wicked be revealed by callunavulgar
Castiel's gone missing, and finding one wayward angel in all of space and time is a bit like finding a needle in a haystack. Good thing he left a message behind—now there's only the matter of figuring out what this mysterious "Rapture" is. In which the splicers have the phone box, the Doctor has an angel for a BFF, Castiel uses a Little Sister for a temporary vessel, and everything’s really about family in the end.

Note: It's also a crossover with the game BioShock.
