Just had an idea for a L&C/ Doctor Who crossover that doesn't have the problem mentioned in another thread of marginlising either The Doctor or Superman.It replaces Army Of Ghosts & Doomsday for Doctor Who, and the New Krypton Arc for Lois & Clark. Here goes....

Instead of invading Who Earth the Daleks & Cybermen end up on L&C Earth, because Beaureu 69 have been stupid and opened the void onto their Earth, so now Clark has to deal with the invaders, which will be tough as he as usual won't want to hurt a living being. For a little extra story here, throw in some revelations about the Daleks having been to Clark's reality before, and maybe setting the red sun of Krypton off on it's ultimate fate because the Kryptonians were (A) non-Dalek lifeforms, and (B) very close to devolping time-travel technology, and/ or some stuff with other characters like Perry, Jimmy, Clark's parents, etc. Lois is of course, by Clark's side throughout the story. At least one person Clark likes gets killed.

Meanwhile in the Whoniverse, the Doctor and Rose have to deal with Torchwood opening the void onto their world, and some villians (Tempus, Smallville's Brainiac, and the movies' General Zod, Non & Ursa). The Doctor can't stop these beings physically so he has to outsmart them. He sees his friend Sarah Jane Smith get killed by one of the above evil people.

At least once in the story, the Doctor & Rose meet and talk with Lois & Clark. At the end the crisis is solved, but Rose & Lois are each on the other's Earth, thereby setting up a sequel.

Any takers?
