You can mount two cogs on any three pronged SA hub. Brompton still does this to halve the gaps in the wide ratio's, or use any two offset cogs mounted back to back
4 speed conversions involved fitting a special driver which accepted -I believe- screw on cogs.
No need for an extra freewheel btw, the one in the hub is sufficient
