The factory seam inside the laz is battered with poly and matt which you may expose. Just open and clean out the loose stuff there on top and fill with epoxy filler, file and fair, paint or gelcoat. Then cut the 1/2 round trim shorter to fit if necessary.
The only downside might be staining on the transom under the openings from water now able to run off the stern.
