As long as you create threads equidistant around the circumference, the balance will stay the same. For example, two bolts 180 degrees apart or 3 bolts 120 degrees apart. But why go to all that trouble? The automakers don't weld nor do they bolt the trigger wheel on. They use an interference press fit.
In between the front and rear? Do you mean between the front and rear V-grooves? You could have that lip machined flat and then have a ring pressed on (interference fit). No welding needed -- the ring doesn't drive anything so there is no load on it. An 1/8" thick trigger wheel works fine so there should be enough space for it.
Here's what one guy did for his Datsun engine twin-groove pulley. You could do similar except put it in the middle of the pulley seeing as your pulley has the room.
