I like this idea of building the modules on top of FR-4 boards. However,
this leaves me unclear on how I should interface the modules to the
backplane. The "postage stamp" idea was appealing, but I am not sure how
I would attach the pins. I know I don't want to be trying to drill very
precise holes, or to be scratching out 20 little islands on the copper.
Any further thoughts on this?

I don't exactly know what  you want to do, but here is one posibility:

Design two double-side PC boards and order some from one of those
cheap houses.

Use mating connectors, D-subs or DINs. The one on an analog board is a
right-angle and the motherboard/patch panel gets straight ones with
wire-wrap tails. Those are available.

The motherboard can do some power bussing. A motherboard could be
short, 3 or 4 connectors, and designed so they can be bolted together
into longer strings.

The baby boards will plug into the mobo and the connectors will hold
them up. Include some common parts like power supply filters and LEDs
and such. Maybe some opamp footprints.

Nice plated holes and ground planes and ways to prototype.

Maybe make an extender board too.

That's almost a product.
