Thank you everyone for the comments, they have been very useful. From the discussions here and internally it seems that neither of these approaches (new target hook for spill location, or using bundles) is the right way forward, and I should look into the pseudo instructions. Since this review has grown quite large I will abandon it and open a new review when I have something working with pseudo expansion.
