I was just pondering, with the skills demonstrated by some of the folks here, why not convert a frigate (like Terpischore) into a merchant? The royal on the mainmast and the t'gallant on the mizzen could be removed. Perhaps the guns could be cut out with an X-acto knife and the ports filled? A base card with sailing arcs like a 74, and maybe some small artillery on the quarterdeck for an aft broadside and broadside firing arc on 1? Just thinking...
