On removing the OGL, I just had a weird idea that could work.
Step 1.- Incorporate a new company (call it Mexican WotC?) in Mexico. And a new Wotc in America.
Step 2.- Desincorporate the original Wotc, give everything but D&D to New WotC. Make Mexican WotC heir to the RPG rights and copyrights.
Step 3.- Have the d&D company issue basically a reprint of the SRD (word by word) as a cheap book. Distribute it worldwide.
Step 4.- Move all licensing to Mexican WotC.
Step 5.- Profit! the OGL stops having effect. (Mexican copyright law makes all rights licensing temporal, and you cannot give them out, and less for free. By making a mexican WotC, all copyrights become established in Mexico, which has a very rigid copyright law, and under it, the OGL isn't legal, by forcing all providers to use Mexican law for contracts they have to accept the MExican law that makes the oGL illegal.)
