Not on your list, but, would you enjoy a crossover with NCIS? My favorite, below: Agents and Hunters http://www.fanfiction.net/s/5385224/1/Agents_and_Hunters
This is SG-1/SGA/SPN, with some ignorable pre-slash: SnaG-22 http://www.wraithbait.com/viewstory.php?sid=15212
For old-school SG-1/SPN, try Maychorian's Jack'n'Dean 'verse: http://maychorian.livejournal.com/48330.html
This is an old wing!fic series, good solid fun. mummyluvr's On Angels' Wings starts here: http://www.fanfiction.net/s/3218212/1/On_Angels_Wings
