i'm not sure how good imperial ship-tech is in regards to non-warp travel speeds, but any speeds they can attain within a galaxy they could sustain intergalactically (and i imagine they could achieve faster intergalactic speed than tyranids do), and they have stasis-tech. at the very least the imperium has the basic requirements for integalactic travel.
