Andrew - drill the holes. Better make them a bit larger than 1/8" as 
the first thing that happens as you start to pull the rivet is that 
the shank swells at the tail end. You don't want that bulge to seize 
in the hole and pull out a patch of layup with it as you squeeze 
further. Afterwards you can fill the holes with flox if you wish, but 
there's not much room for manoeuvre in there even after pulling the 
rivets.

Don't try to push the rivet heads down as you snap them, because it's 
highly likely you won't manage it successfully. If the heads aren't 
down tight onto the countersink you made, then they aren't providing 
adequate holding strength & location for the hinges, and that's much 
worse news than any cosmetic shortcomings!

Rowland
