Thematic Search: Stargate/Sentinel crossovers

[margarks.livejournal.com]

Looking for lists or recs of Stargate/Sentinel crossovers with either SG1 or Atlantis (no Universe please, since I never watched that one).

Gen or slash (Jim/Blair, Jack/Daniel, John/Rodney) would be my preference, but any recs are welcome. And any slash pairings, really, the above are just my favs :)

I would like it to actually have Jim and Blair in it, though, if possible, not just the Stargate characters turning out to be Sentinels or Guides.

Thanks in advance for your help!
