If you are going to do something like that, could you heat up the whole
assembly in a toaster oven with solder paste like they do for SMT
devices? Would save you having to mess around with 100W irons I think,
maybe even cause less thermal stress as the whole assembly, rather than
little points, would be heated.

Depends if the diodes can take a reflow cycle of course.
