Really no harm in trying regardless we would think.
I finally found an agent on the phone at Chase that told me that refunds on B6 tix go to a B6 bank that is kept at Chase, in the name of the UR holder, not the B6 flyer, though the credit goes towards the B6 flyer, if that flyer is not the Chase acct owner. They also told me that the amount is indeed forfeited if one uses the travel bank on a lesser fare.
