Tony, your first toe rail mockup made me think of the BCCs...
This particular one opted to go the paint-it route - looks good too!
Nice secure deck with those bulwarks...
...Then you pulled out those bronze rail chocks. You should definitely design around those babies!
How about a toe rail treatment similar to your coamings? Build them up with fiberglass - you wouldn't have to worry about thru-bolting. Then, you could top them off with a nice mahogany cap so you'd still have something to varnish.
