This may not solve the spoke breakage problem, because that could lie
with the wheel builder, but 36-spoke is certainly along my thinking.

I'm for that but why two different rim and hub types? Get front and
rear 36-spoke wheels and ride the same tire front and rear. If you
put on many miles, you'll realize that replacing tires, tubes, rims,
and spokes is a lot more convenient if they are the same front and
rear, although spoke length is probably a couple of mm different.

Very true but the smaller and necessarily harder tire puts more
vibrating stress, the stress that causes failures, to be exerted on
all components between road and saddle.

Of course, and cornering traction is better, if you do that sort of
thing, because more road contact is maintained over rough pavement.
I don't worry about how you will be judged for riding 36-spokes or
pedaling at cadences under 100 (as is common here). Get out there
