Well, in lieu of Harry/John fic, I can offer you a Harry is John fic: Songs Across the Ocean (http://mhalachaiswords.livejournal.com/188552.html) by mhalachai. I will warn you that the sequel, Ancient Blood (http://mhalachaiswords.livejournal.com/192871.html), does have het, though I got some slashy vibes from it too.
Oma's Choice http://www.fanfiction.net/s/5931066/1/Omas_Choice is an unfinished HP/SGA crossover, it's good but no parings have really been put in motion yet
The Lazarus Curse by Gaia / gaiaanarchy (McKay/Sheppard): John Sheppard is not who he seems. Rodney dedicates himself to figuring out what’s wrong with his oddly-distant lover at the same time as a mysterious man sets out on a journey to find Atlantis. (John Sheppard=James Potter)
I'm a big fan of HP/SGA crossovers. I've included some gen in case you are interested.
Harry Potter and the Legacy of the Ancients by jacksez http://www.fanfiction.net/s/6283614/1/Harry_Potter_and_the_Legacy_of_the_Ancients 15,730 words, wip, last update 9-21-10, past hp/rw, hp/john. After defeating Voldemort, Harry Potter leaves the Wizarding World but after connecting up with Dr. Daniel Jackson through his new school he is off on an intergalactic adventure.
Of Misery and Mystery by TheWingedWhispered http://www.fanfiction.net/s/3852272/1/Of_Misery_and_Mystery 44,797 words, wip, last update 7-11-08, hp/john. Captured by the Wraith, John Sheppard is freed by a man identifying himself only as Harry. He is then thrust into another world and another war. Will he ever find out why the elusive Harry is so interested in him?
Walk of Life by Solunvar http://sites.google.com/site/solunvar/stranded/wol abandoned wip but worth a read, 23,000+ words, gen & minor het. Accidents have consequences, a fragile Horcrux creation rite even more so. Given a little push, even DNA collapses; what happens when magic can fill the void and rebuild our genetic structure?
The Astria Porta Project by Solunvar http://sites.google.com/site/solunvar/complete/tapp 25,000+ words, abandoned wip but interesting, gen with minor het. The United Kingdom was the region Moros was active in the most. Centuries after his ‘departure’, the findings of several of his possessions herald a new age for mankind on Earth with the Commonwealth concurring the Americans’ SGC.
John Sheppard and the Veil of Merlin by springwoof http://springwoof.livejournal.com/13179.html <5,000 words, mckay/dex, sheppard/sirius. “So you’re telling me that this dog has the Ancient gene, Colonel?” crack!fic
John: Hero by Day, Death Eater by Night by eleveninches http://eleveninches.livejournal.com/214867.html <5,000 words, gen, John as Regulas Black, crack!fic.
Go Far by skoosiepants http://skoosiepants.livejournal.com/151799.html <5,000 words, Draco/Ron. Fusion fic. Ron is a xenobiologist, Hermione is some sort of researcher & Draco is a physicist & good in the field. Draco saves Ron's life three times which on Atlantis is synonymous with courtship.
Clarke's Law by isiscolo http://hieroglyfics.net/clarkeslaw.htm 20,000 words, fun gen. Any sufficiently advanced technology is indistinguishable from magic.
The Light Brigade by Ravenfur http://www.fanfiction.net/s/4153543/1/The_Light_Brigade 25,000+ words, hp/rodney, harry as sheppard. Elements of Lt. Col. John Sheppard's past come to light when the Daedalus brings reinforcements to Atlantis.
The Soul Has Bandaged Moments by serendu http://www.fanfiction.net/s/3020580/1/The_Soul_Has_Bandaged_Moments 50,000+ words, gen. Harry Potter was 18 when he first stepped into Atlantis.
Undone Wars by esama http://www.fanfiction.net/s/5839924/1/Undone_Wars 47,000+ words, hp/ronan. The life of a Runner is hell, but even hell doesn't seem so bad when you have decent company.
Space haven by esama http://www.fanfiction.net/s/5233108/1/Space_haven 125,000+ words, no pairings yet. Harry won a battle only to see that the war still continued. Now trapped inside Hogwarts with no way out, he and the others search for a place to make their final stand in. Thankfully they receive a little help from thousand years ago.
Heritage of the Ancients by wolfwalker http://www.hpfandom.net/eff/viewstory.php?sid=15838 100,000+ words, hp/jack. Ever wonder where magical folks really came from. Ever wonder why the Ancients never sent out a rescue ship for their brethren in the Pegasus Galaxy. Finding out his true heritage Harry found out and now it is time to do something.
