Really well thought out theory, but I have some problems with it.
1. I don't see Luffy taking a child with him. We can talk all day about what Roger did, but it's Shanks that I see Luffy really modeling himself after, and Shanks refused to take him along.
2. Yes, Oden went with Whitebeard and Roger. And it led to the downfall of Wano. Had Oden been there to stop Orochi and those elders, it's possible that none of this would have happened. I don't see Momo wanting to make his dad's mistake. Plus, his sister hasn't seen him in 20 years. She deserves to spend time with him... When she isn't busy with her Shogun duties.
3. I don't want Pudding to join. She was an obnoxious character. Plus, she's not in Wano and I doubt Sanji would want to go back to get her.
4. I believe Monet is very, very dead.
