Not an ARIN example but when KPNQwest went out of business, the situation 
was as you desribe and it would have been difficult to everybody to quickly
renumber so their PA assigned customer ip blocks with assistance of RIPE 
became PI blocks (at least this is how I understood it, people in europe 
can correct me if this is not right). So the precidents do exist, but 
they involve having RIR take over the block.
