My ultimate goal is to take the Doctor on a journey to the farthest regions of the galaxy and across the event horizon. He literally goes everywhere he can to look for his planet, with no luck. Somehow, though, the dots connect at each place he visits and he realizes the truth about where the planet is.

I had forgotten about "Amy's Choice" when I proposed the two realities idea. It was a way I thought we could show the two sides of the Doctor's personality (cold and tough vs. vulnerable and afraid), and since one of the realities is somehow inside the Doctor's mind, it'd be a plausible place for him to find Gallifrey or discover the truth about its location, at least. Eventually the two realities would become one, meaning the Doctor would connect the dots to Gallifrey's location in one reality, while he'd find it in the other. Or something like that. This makes a lot more sense in my head :P

I don't think you understood what I was saying in regards to the Ice Warriors/King Arthur thing. I was not trying to suggest a King Arthur story with Ice Warriors in it. What I was trying to do was show you what I meant by "take an existing story and Doctor Who-ify it." My example was this, the plot of "The Warrior's Sowrd":
 * The Ceremonial Sword of Lord Slazaxyr The World Bringer has been lost for thousands of years, and a troop of Ice Warriors, now peaceful inhabitants of the universe, has come to New Mars in order to find it, hoping it acts as the key to an energy bank that will reinvigorate the power grid of a long-established but now decaying city (as well as the life-support systems that keep the million or more inhabitants alive and cold). The Ice Warriors have a traitor in their midst, though, a killer who picks off their number and is mistaken to be the Doctor.
 * When the Doctor arrives on New Mars, he has a bad feeling about the Ice Warriors' search for the Sword. He is made to act as a guide through a trap-laden labyrinth; when they find the Sword, neither the Doctor nor Ice Lord Makara are able to remove it from the plinth of unmeltable ice. Warrior Izlak dislodges the Sword; he is revealed to be the killer, and he hopes to use the Sword to make himself the first Ice King. This warlike spirit is recognized by a genetic imprint in the sword, which rewrites Izlak's genetic code and returns his latent thirst for conquest. A simple touch from the corrupted Izlak taints Makara; the Doctor has to return to the decaying Ice Warrior city before the two born-again Ice Warriors can infect its millions with the spirit of conquest that was the nature of Slazaxyr.
 * As the genetic rewriting runs rampant, the Doctor is forced to destroy the city, along with its previously innocent citizens….

From this, you can see some of the "Sword in the Stone" elements that serve as the basis of the story; just as Arthur is the one to remove the sword from the stone and become king in his story, the murderous Izlak is the one who removes Slazaxyr's sword from the ice that holds it in his effort to become the first Ice King.
