Have you seen the step-down butt connectors ? http://www.go2marine.com/product.do?no=83250F&WT.mc_id=gb1
I did exactly what you are talking about with my Alpenglows, but I used a terminal strip, sprayed it with T9 or other non-corrosive, it was in a dry location and I didn't have an access issue.
I heard you packed it in already, hope it was a good season, I was thinking about our sail today, your boat is FAST.
