I found this online:

but having never encountered this pedal I don't know if the process is
peculiar to this brand/model.

Any similar success stories?

Any 1/2" pedal recommendations? I don't want aggressive bmx platforms
but neither do I want flats with rubber coated platforms. The principal
stipulation is that they're 'big enough'.

I'm not familiar with platform pedals designed for bmx use.

The pedal in the article was described by Sheldon Brown: "The best known
platform pedal was the French Lyotard "Marcel Berthet" model 23, one of
the most elegantly designed bicycle parts ever." It's definitely worth
jumping hoops by cannibalizing other pedals to get a working pair of
these gems on one's road bike.

For more mundane models, I second Mr. landotter's advice to find a pedal
with the proper threading.

'Platform pedal' may have various meanings.

Trendy candy color platforms are big this year:

or of course the staid old silver and black aluminum
versions. Big selection under $20 (to well past $100)

Having ridden many Lyotard #23TF and #23, I found the tops
of the aluminum sideplate stampings will wear through in
about 8~10 years of daily use, at which point the pedal
self-disassembles. Dust caps are only tenuously secured by a
fine poor fit thread and caps are amazingly difficult to
find now. A $15 Gitane on craigslist was the cheapest source
for my last cap.

Copies have been made, generally of much better quality,
once by SR-Sakae and now from White Industries but they lack
the svelte French aesthetic of thin stamped plates.
