There are at least a dozen publically available codebases that are 
amenable to commercial exploitation.  Some are GPLed.  Some are free.
Some are licensible.  Why the concentration on Diku and Diku-derived

No this is illegal and dare I suggest unethical.  
There isn't any way one can GPL a DIKU derivative codebase short of
the Diku authors GPLing it themselves.

The former.  The latter cannot remove restrictions placed by the former
they can only add additional restrictions.

No.  Copyright law is not murky.  It is not untested or uncharted 
waters.  It is crystal clear.  I've already posted several 
references on this exact topic in r.g.m.d.  You cannot force someone 
to GPL their code.  GPLing modifications to an original work does not 
give you permission to violate the license to that original work 
because modifications plus that original work created a derivative work 
which is still under the original license.
