[Star Trek DS9/Voyager] How might things have played out differently for both series if the Bajoran wormhole ended in the Delta Quadrant and Voyager was thrown into the Gamma Quadrant?

Not complete by any means, but just a few thoughts on the matter...

From the Romulan side, the Dominion War wouldn't have happened so they (most likely) wouldn't have pressed the Remans so aggressively into service and relied so heavily on them as shock troops and weaponsmiths/shipbuilders.  This would prevent the rise of Praetor Shinzon and the annihilation of the Romulan Senate.  Instead of the Romulans becoming tenative allies with the Federation following the Nemesis Incident, they would have maintained their aggressive and meddlesome activities in the Alpha Quadrant.

The Klingon Empire really received a much needed morale boost with the dawn of the Dominion War.  They were a stagnant, listless society and a pawn being played with between the Federation and the Romulan Star Empire.  Mobilizing and uniting the entire Klingon Empire to crusade in glorious battle reignited a passion in these proud warriors.  This brought them respect and fear placing them once again as a major player in the Alpha Quadrant.

With the Borg *so* much closer to the Federation than ever before, the Federation would ramp up to a war footing that made their recovery from Wolf 359 up to the Dominion War look like a recess at elementary school.  The dogs of war were already barking loudly at Starfleet Command and with a massive and imminent Borg threat at their doorstep, the military would be given levels of power and control never before seen in the history of the Federation.  Frankly, this could even possibly lead to the rise of a prime universe Terran Empire akin to its dark mirror universe cousin.
