Based on the description of the history of the project, it sounds like all the 
previous developers were employed to work on the project, in which case it 
seems likely that Monica's company owns the copyright to the entire codebase, 
in which case you'd need to talk to Monica (or whoever the current CEO is) 
about changing the licence.

However, if the last version of KTooN was GPL2, and you've written everything 
that has been added since yourself, there should be no problem officially 
changing Tupi to GPL2 to make it a KDE project, without needing any permission 
from Monica's company.
