The LED would need a rectifier of course.

You just parallel a reverse connected diode to the LED for AC. Plus a
suitable current limiting resistor, of course.

you can, but the resulting flicker is terrible. Worth going for 100Hz
flicker imho. That also gets you half the capacitor size.

How about a pair of LEDs, reversed and paralleled, and mounted very
close to each other (perhaps behind the same diffuser)?

And there must be a reason why you can't connect the diode pair in
series with the load, otherwise it would have been suggested by now.
What's the reason?

You can put a diode in series with the LED. But... you then need a
leakage resistor across the LED, you get bad flicker, and you can only
use an R dropper, not a CR.
