Re: Dr Who/Star Trek Crossover WAS planned by RTD
you have Doctor Who crossover with Star Trek, not seriously, you could have him trapped on a planet that has based its development on Star Trek, but not an actual crossover. There is no way you could match the timelines.
I like the idea of having a planet or culture that bases itself based off the holorecordings found in a crashed ship, the show on the Holorecordings, "Star Trek".
Laws only work if everyone is honest, no piece of paper is going to stop a truly deranged person from doing something atrocious.
