I would take the wedges out to glue the cracks with wood glue. To press first a foil and then put some cardboard pieces on the picture side before attaching the screw clamps with underlay woods. Fill the cracks thoroughly and let it dry overnight in the pressed condition. If glue has reached the grooves, then brush it out moist after tightening the screw clamps in order to be able to insert the wedges again later. When inserting the wedges, you should be more careful than before the cracks. For trouble, you would have to grind them a bit thinner or shorten the tip if they do not fit well in the grooves.
