Patrick,

I've never been faced with this particular problem, but I have a tool 
that I think could do the job.  It's sold as a broken screw remover.  It 
looks like a miniature hole saw.  It's a steel tube 1/4" diameter by 2" 
long, with sawteeth ground in the end.  All you need is a reversing 
drill (the teeth are set for reverse rotation).  And you'll have to plug 
the hole, then drill for the replacement backcheck wire.
