[Die Hard] Did Hans have a Plan B in case the FBI decided against cutting the electricity?

He knew their standard operating procedures.  The only reason the FBI wouldn't have cut the power would have been if they didn't believe it was a terrorist takeover, also known as an A-7 scenario.  Hans would have upped the ante and began executing hostages in order to convince them.  

If for some reason that didn't work, they had enough C4 to flatten a city block.  They could've blown the safe along with the building and slipped out with the bearer bonds in the confusion.
