You lost me regarding the copper losses. The doubler causes 2X the current at the transformer's secondary for a given PS output power (vs the usual full wave supply). If the secondary wire gauge isn't upgraded to accommodate this, losses will be higher. I'm with you regarding the diodes, although they did know how to series them back then. I have an RF amplifier with a 1,500 VDC @ 1A supply from the early '60s. It's all solid-state using strings of diodes (four 811As as finals).
Yes, I've looked at a few of the other doubler circuits. They all seem to have some drawback when I SPICE them, usually more difficult to overcome than this one.
