The Blue Press, the Dillon reloading catalog has a ladder rear sight that I am considering for my two Cowboys, one 1895 and 336 cowboy in 30-30, I think it would look pretty slick, and be very functional, though you would not get as good a groups as with a peep sight, but I can live with that. I have peep sights on some of my other rifles. Variety is the spice of life.
