With all of the discussions about Shinji Ikari having a different person raise him, how about applying the same thing to Harry Potter.
Imagine the mayhem in Hogwarts with some people.
Perhaps Vernon has a meeting in SanFran leaving Harry to accidentally stow away on the captured Klingon ship from Star Trek IV and is raised by Kirk and company some distance in the future. Or even him ending up on Voyager during their time in the "present". Hell, Harry raised by Q could end up being quite entertaining, perhaps him making the kid into a Q (as he offered several members of Picards crew.)
Him stumbling onto the TARDIS and adventuring with the Doctor could also end up crazy.
How about him being raised by his cousin Robert Muldoon (A squib cousin of James') leading to Hagrid showing up on Ilsa Nubular just before the events of Jurassic Park. Would Hagrid ever leave the island once he found out, or him trying to smuggle a Raptor back as a new pet. Harry taking a "prototype dinosaur pet" to Hogwarts with him leading to a Malfoy Vs. Mini-Raptor on several occasions.
If Muldoon dies as in the movie, then perhaps he'd convinced Hammond to take Harry in leading to Harry as the pseudo-cousin of Tim & Lex.
