This has the potential to be great. I wonder if this will be another crossover between the universes, or if the Xenomorphs will be native to the Star Trek universe? I could see either one working this time.
I'd prefer a story where the Xenomorphs are native to the Star Trek universe. In the Tipton's own Star Trek/Doctor Who, they indicated that the Slitheen exist in the Star Trek universe when the Doctor shows Picard the Cyber-converted Slitheen and suggested that Picard should be familiar with them.
I'd go further than the Xenomorphs. I'd also like to see Weyland-Yutani as part of the Star Trek universe. For instance, was Noonien Soong influenced by WY's androids in his creation of Lore and Data?
