Yes, we operate this way at our airport. The original poster was
considering "formal" designation with separate markings, etc. That
would involve the FAA, paper work filing, a site visit possibly, and
definitely a refusal. All of that together with a refusal would likely
cause a municipal airport authority to become frightened and stop the
operation.

If you look into the CFRs about parallel runways you will find that

must be separated by 750ft, IIRC. This means you cannot "formally
designate" a second runway with markings, etc. at your site.

There are lots of airports where gliders operate from the grass
alongside
the paved runway, but none of these are designated as separate
runways.

3B3, in Sterling, Mass., home of the very active (150+ members)
Greater Boston Soaring Club and MIT Soaring Association, is set up
this way. The parallel grass strip is well maintained, but I do not
believe it is listed as a separate runway. Landing pilots sequence,
and when announcing on CTAF, we simply state "taking the grass." If
power traffic is on final, launches from the grid are definitely put
on hold
