I have a set of the WWII plastic extended target grips that the gov't spec'ed from Colt. While not elephant ear grips, they do work a treat on Series I Woodsmans. They're collectable and a bit pricey in their own right but turn up with a fair degree of frequency.
I have small-ish hands and actually rather like the standard grips on Series I's.
