No, that will not help.

It could be that they aren't sufficiently creative to merit copyright,
in which case they already are public domain.  I doubt this, though;
generating test sets requires thought.

Or, if they are copyrighted, and you want to use them other than under
the GPL, you need permission from the authors/copyright holders.

If there is a test data set, though - what's the problem with GPL?  It
can be installed as a package, with inputs and outputs, and then
programs of whatever license (even gasp a proprietary licensse) can be
run on the inputs and the outputs compared.  Or is it that you already
have a big PD set and want to enhance it?
