Nice try, but I highly doubt that it'll work out. Your code is a derived work 
of GPL'ed code (even using tricks like glue code doesn't help _per se_; not 
to be derived work would mean that the code can reasonably work without using 
any GPL-only bits ...).
So you can't prevent the copyright holders of the GPL'ed code you're using 
from enforcing the license (except if they did some dual-licensing or gave 
you explicit permission allowing you to use their code in this way).
