That is completely not possible.  Once you offer (and someone accepts)
code under the terms of the GPL, they are for evermore entitled to use
*that* code under the GPL.  About the only thing that can be done is
to quite releasing new versions of the software or release newer
versions under a more restrictive license.  That, or hope everyone
who receives the code violates the GPL (since that is about the only
you lose your rights under it after the fact).

But it can't be done, period.

"In order for these freedoms to be real, they must be irrevocable as
long as you do nothing wrong; if the developer of the software has the
power to revoke the license, without your doing anything to give cause,
the software is not free."
