I see, so the worry about a seat tube would be related to a tendency to use a small-diameter seat post. Cutting down a post of a common size, say 25.4mm, 26.4mm, 27.2mm, whatever, makes fine sense to me.

FWIW, here's an idea of a bike I might try to copy if I were to make a frame. Maybe make a unisex stepthrough version a la Rivendell Cheviot since the horizontal top tube is pretty high. It's pretty heavy for its size, and being a cheap bike from the '80s means steel rims and cranks, but otherwise seems (to me) to be superlatively desirable for families like mine who use bikes primarily for in-town errand running - and no one seems to be making one like this these days, thus the point in maybe going to the bother of making one.
