That's fine, but it won't make what you're working on a 4.75 like Pathfinder is a 3.75 - Pathfinder can re-print all the classes, races, spells, items & monsters from the OGL, whole-cloth, making the game not only D&D-3.5 compatible, but giving it the same core of character & DM choices as the original game.I'm pretty sure that's not how Copyright works. First you can't copyright game mechanics. Second you don't copyright each individual section, you copyright the work. Third Advantage has a different meaning to in Next - which is a different game to 4E anyway. And as I'm writing the rules text from scratch and taking inspiration from a dozen different games I don't think there's an issue.
You absolutely cannot do that for 4e.
