In my opinion, this cracked bridge could be much more easily and effectively repaired by using a medium viscosity CA glue, such as Dryburgh's or Alteco, or any of a host of other "industrial strength" CA products. Remove the strings from this section, or at least get them out of the way, straighten up the bridge pins and dam up any cracks which might allow glue to run onto the board. Dribble glue into the cracks until the wood around them is saturated and the glue begins to pool around the pins. Hit the bridge with accelerator, and voila'; a permanent repair in record time. One caveat: make sure you get everything where you want it BEFORE you set it with accelerator. Once done, a CA repair CANNOT be undone.
