On further (and more sober) reflection I would probably 
answer like this:

No way, no how, if you have a named structure. If you
have an anonymous structure you *could* (under extreme
duress) simply redefine the structure without the
*&%%$^ field:

   struct = { a:0, b:0, c:0}
   struct = { a:struct.a, b:struct.b }

Cheers,

David
