Yes, this map here (with all the Alpha and Beta Quadrant Most known Species we know [before Voyager's Delta Quadrant Trek]), seems much more realistic to me, with the Alpha and beta Quadrant powers we are familiar with all bunched up close to the separator line between the Alpha and beta Quadrants
Also, even on this map, the Dominion Space is huge, and it's just a fraction of the Gamma Quadrant.

Where are we going? And why are we in this Handbasket?
