That's one reason highway pegs were so popular, they'd allow you to change position. Back when my bikes were newish, I ran the hoop type highway bars and switched between them, the regular pegs, and the passsenger pegs on long rides.
I'm with the OP, I like the look of the stock seat, but for me they're too tall and wide for me to be really comfortable, and while most bucket seats are comfortable most of them are taller than stock so they're no good, so most of my bikes have had cafe style seats on them.
