Bach's only fugues that I'm aware of in C major are 531, 545, 547, 553, 564, 946 (beside 846 and 953, which you already mentioned - though they each have C major fugues in them). I'm afraid I don't have that edition of Dupre, so I can't help any more than that. I'm pretty sure he never transposed Bach though! He used to play every Bach organ piece from memory!
