I think it is definitely worth a try. It looks like it doesn't have tip overlays in the first place. I would rework both tips by adding a base layer of fiberglass over the tips, long enough to cover the cracks on the damaged end (make them match). then some phenolic, or more glass or wood to finish them off. On the belly side where the string groove is damaged, it looks like it is an extra piece of wood glued on top of the green glass. I would carefully sand it off on both tips, and glue up replacements. I would probably go with more glass and cut in shallower grooves.
