I finally got around making a custom dress form! Here it is wearing a corset I made last year. Better photos coming soon.
I made it using my usual bodice block pattern (drafted following instructions from a 1901 book), which I adjusted slightly to make sure it was as close fitting as possible. The result is pretty accurate to my measurements when wearing all the appropriate underpinnings, although I overstuffed the ribcage and waist, which you can tell by comparing the above and below photos - the "naked" dress form should technically have the same shape as the corseted one. That's problem for future me.
I still need to make the caps for the armholes and attach the neck cap properly, but it is functional.
