I looked in the Federation Milky Way map and I noticed that if USS Voyager would have chosen a different route rather than going straight home they could have made back faster. They could have traveled from the Delta Quadrant to the Gamma Quadrant and used the Bajoran wormhole to get home. I measured the Caretaker Array was around 40,000 light years to the Bajoran Wormhole. Instead they tried to travel 70,000 light years home. They would have come across the Dominion but they've beaten the Borg and Hyrogen so I think it would have been done.
