My favorite thread revived?! YAY!
Yes, as I recall, travel through the warp itself does require an actual psychic presense, so that could be a way for them to escape.
However, the Borg themselves aren't completely without "psykers" of a sort. There are many races in Star Trek with telepathic and telekinetic abilites. Admitedly, with the likes of the Vulcans it can take a lifetime of experiance, training and discipline to even begin to approach the kind of power 40K psykers have, but for some other races, such as the Betazoids or the Okampans, Psychic powers can manifest into abilities that dwarf those of even the Eldar Farseers (pic related).
The hiccup then is 1) If the borg's psykers can provide the collective with the means to navigate the warp and 2) How they would figure out how to do it. 2 is easy, it just requires assimilating the right person. 1 is trickier, and depends a lot on exactly how warp navigation is performed and if Star Trek psychic abilites are "compatible"
