Are there any Doujinshi novels related to One Piece?

I remember reading a novel in the past. The main character transmigrated into the world of One Piece and became the big brother of Ace, Luffy, and Sabot. The main character was recruited into the navy by Capra and became a general in a few years. He changed the fate of Ace and Aokiji and hooked up with the three generals of the Aunty Pirates, Smudge. I forgot the title!
