If Primeval had a crossover with something, what would you like it to be?

I THINK DOCTOR WHO, BECAUSE HE TRAVELS IN TIME AND THE ANOMALIES ARE TIME GATEWAYS. MAYBE THE DOCTOR COULD HELP THEM FIND OUT mais ABOUT THE ANOMALIES.

As a fã of Merlin aswell I would like a crossover between them. Could make a good shortie for Comic Releif or something? I'm sure Merlin would amor the 21st century, and Connor would probably be really geeky about meeting mythical legends like him and Arthur.

DOCTOR WHO AND JURASSIC PARK.
