[Avodah] O attend R wedding = kosher eidim?

Was: Re: [Areivim] R & R concerts

The subject shifted to Orthodox eidim at a Reform wedding:

R' Toby Katz noted that Reb Moshe Feinstein ruled that R eidim are
unkosher, and thus, there is no wedding, no need for a get, no
mamzerim.

And besides, maybe we could play like R' Akiva in the Sanhedrin, i.e.
(hypothetically) ask impossible questions? Could this O guy tell me
exactly how long it took to say the brachot, or exactly how full the
kos was? Or what brand of wine was used? Oh well, I guess he's not a
witness...

If this works, would you have to actually ask the O guy the questions,
or could we just assume he doesn't know the answers and declare him,
automatically, not an eid?
