Yes, I have tried this, and it does indeed work.  In fact, you can
now buy "disk punchers" that poke nice square holes for you to accomplish
the task.  The only problem is that the (normally) 800K disks aren't
inspected or made to handle the high density of data of a 1.44 Mb floppy.
Hence, I've experienced roughly a 20% failure rate of disks treated in
this manner.  The simply won't initialize.  I've never lost any data
on those that did initialize though.  Sort of a "use at your own
risk" thing.
