Had a similar issue last year DUB->ATL on DL. Flight was oversold (baggage was already being loaded), but we were able to VDB for $1000/ea, overnight hotel, and D1 return from LHR the next day. They pulled our 4 checked bags (2 suitcases, 2 sets of golf clubs) off and walked us back through security. That part was easy. The next day turned into quite the debacle, though.
