I see that at Uberti they've been playing with period styling, and have introduced an SAA clone with an octagonal barrel. Neither Colt nor the Remington 1875/1890 had an octagonal barrel, but some period firearms did, and it's not bad looking.
But now for some reason I'm imagining an SAA clone with a tapered "pencil barrel" profile like you see on older S&W duty revolvers in .38 Special, complete with the prewar style round "half nickel" front sight that was semicircular in profile. And a slightly altered topstrap at the rear for a proper Patridge style square notch rear sight with that portion of the topstrap level on either side. Would it look like some kind of generic early 20th Century firearm? Probably not, it'd probably look silly.
