New larger scuppers

I've discovered my scuppers are leaking into the cabin (1983 H31). While fixing the leak, I'm thinking of enlarging the scuppers. A search on that topic led me to an interesting post by DianaOfBurlington (then posting under his real name):

"A stronger and less fallible way is to fiberglass a G-10 tube straight between the cockpit and the hull connecting a 1-1/2" hole drilled in the cockpit floor and the hull at each corner. This avoids the hose, the need for a seacock, and about 95 percent of the vulnerability. It will also lend strength to the cockpit sole (the tubes will serve as legs). One drawback is the amount of work it will take. But the asset is in knowing that the cockpit water goes directly out of the boat and not through a vulnerable hose."

Has anyone tried this? Any thoughts on how difficult it would be? How do you make the new above-the-waterline hole in the topsides (one on starboard side, one on the port) look "pretty"?
