The reason: My local airport's altimeter setting can ONLY be received on
the ADF. Without being able to receive that frequency, I have to use a
remote altimeter setting, and the MDA is increased by 160'

What approach is that?

Any of the approaches to EPM. There are two NDB, one overlay GPS, and one
stand-alone GPS

Does the plate say "ADF Required"?

No. But it's handy to have if you are executing one of the NDB approaches
and don't have a GPS :-)).

If not, I
wonder if it would be legal to get the altimeter with a garden-variety
AM radio.

Perfectly legal. In addition, if there were someone on the ground, they
could relay the information via Unicomm.

But I've not seen a garden-variety AM receiver that would tune to 260. If
you know of one, please let me know. The one's I've seen don't go much
below the AM broadcast band.
