This method is problematic.  For one thing, removing a portion of a
monitor from the gray region will confuse the Finder, and it will start
repositioning any icons which happened to have been located under that
window.

Another issue is that, once your window is off the gray region, the
window manager wants nothing to do with you, so you end up doing most
window management chores manually.

The most serious problem is that punching a hole assumes that you can
unpunch the hole later (if the window moves or closes).  That requires
knowing what the gray region should be, but what it was when you
punched the hole may not be what it is when you attempt to unpunch the
hole.  (The gray rgn changes if, say, one of the monitors has moved.)
It is not safe to assume that the gray region should be restored to
whatever it was when the hole was punched.

Sorry, but at present I don't know of a good answer on how to proceed
on this.
