Sorry, but I'm confused.
Are you basically saying abandon the standard method and simply drill holes through the trim and screw it on into sort of rawlplugs pressed into the sill?
The trim moulding has a flatter section below the central raised portion, so the screws are partly shielded from view, and if countersunk would be flush in the plastic and in any case could be painted black or covered with some black sealant.
But the standard clips hold the centre of the trim - this suggestion pulls the lower section. Doesn't that mean the upper edge is attached less firmly and risks letting water in as it runs over the sill? Or are you suggesting setting the whole trim in sealant?
