The new style hub will certainly imrove the clearance as will machining the wheel mounting face of the old hub to move the wheel slightly to the right; some people have done this.
What I would question is what are you calling correct alignment? Don't rely on measuring or counting threads on the adjusters to make them equal; they're not equal to start with and the bearing bars in the adjusters tend to bend and become even less equal. My way of getting the adjustment rght is to spin the back wheel by hand backwards and forwards between tweaks to the alignment until the belt stays in the same place on the back sprocket, i.e. it doesn't wander from side to side, then adjust the tension by equal turns on the adjusters. The belt will be overhanging the outside edge of the sprocket by about 4mm or so when it is set correctly.
