"Make it Geronimo?"
Of course, Star Trek has been repeatedly mentioned as a work of fiction in Doctor Who and its spinoffs, and the two universes follow very different ground rules anyway, so this would only work as an "imaginary story" type of thing (unless the TARDIS has found its way into the Land of Fiction once again).
I can't see them playing it that way. Besides didn't one of the DW producers want to do a crossover with "Enterprise"? So it's entirely possible that they're going to play this straight.
Russell T. Davies wanted to do a crossover, yes. He's mentioned it several times in interviews, and he wanted Julie Gardner to approach Paramount, only UPN had gone and canceled Enterprise
by that time.
It's thought that the Enterprise
crossover episode would have filled the "Boomtown" spot in the first season, which was itself a replacement for another script that fell through, Paul Abbott's "Pompeii."
