USE YOUR LAWYERLY BRAIN!!!

Pretty much ANY large GPL project will not have all its Corresponding Source licenced under the GPL. The linux kernel for one. LibreOffice for another.

What happens if you take SOMEONE ELSE'S eg MIT-licenced code and include it in your GPL project? YOU CANNOT RELICENCE THEIR CODE.

The project as a whole can only be safely distributed under the GPL - that is the intent and magic of the GPL. But each piece of the Corresponding Source is licenced according to the ORIGINAL AUTHOR, and needn't be GPL at all.

Ask yourself this simple question - "If I include someone else's NON-GPL code in my project, how do I re-licence it for release under the GPL?" The answer is YOU CAN'T.
