Before i write my post i should probably make clear that these are solely my personal opinions and feelings about the characters, so be friendly with your critism.
First off, Kinemon. He is probably the funniest non-SH character we´ve seen in a long time, especially after the rather dark and sad Impel Down, Marineford and FI arcs. I have to admit that his inappropriate pride and also "pervertness" are really refreshing. He also looks good with the SH, especially his "battle face" stands out. These positive aspects of Kinemon don´t make him an acceptable NN though. Although his quirks are a bit different, in the end he´s still too similar to other SHs, it´s like he´s a mix of Zoro, Sanji and Brook. Besides, unlike most of you guys i find him being another swordsman not unique enough for the SH. Most of the OP characters can use swords as far as i´m concerned but the members of the SHs should be unique. For example, even though Brook also uses a sword like Zoro, Brook´s primary fighting style is his DF, he either hypnotises his opponents or uses his soul to freeze his sword. Next point, the elephant in the room so to speak, is his son. Kinemon doesn´t strike me as a person who would leave his son behind, no matter what the reason. The comparison to Yasopp just doesn´t make sense because him and Kinemon have totally different backgrounds. Yasopp is a free spirit who although feeling bad about leaving his family behind couldn´t help himself but choose the life of a pirate. Kinemon is from Wano Kuni (modeled after feudal Japan) in which duty and honor stands above eyerything else. There at least shouldn´t be anything that makes Kinemon forsake his duty as a father.
Next Monet. At least partly, i understand the hype around her and the discussion about her being the NN. Honestly, a beautiful harpy is just awesome and unique for the SHs, especially if you compare her to Kinemon. Other than that though, i don´t see anything that makes her SH material. She is, at least till now, way too similar to Robin. Cool and calculating, highly intelligent with a healthy curiosity in science and knowledge in general. That still would be acceptable if a unique quirk were to be introduced later. The biggest difference to Robin though is that for me, she can´t redeem herself. In Robin´s case, you could already tell during the Alabasta Arc that she is a bit different than the other member of BW (the logpost to an island near Alabasta, her saving Luffy out of the sand). Monet on the other hand doesn´t have any of those redeeming actions (maybe the note was from her, ok) but most importantly her tolerating experiments on children ist just a no-go, especially for the SH. Besides, the twist that she actually works for Flamingo is good enough, i don´t need another twist saying she works with Law or wants to befriend the SH.
I´m gonna quote my opinion to Jinbe from another Forum:
Jinbe clearly stated that he can´t stay on Fishman Island because of his status as a criminal. Him staying on FI would only jeopardise the Royal Family´s plans to emmigrate onto the surface. Of course he could try to hide near FI like Decken in order to protect it but it shouldn´t be forgotten that Decken was "only" a national criminal whereas Jinbe is a world famous pirate for whom the WG definitely would come to search on and around FI. Besides, the Kraken, the 70000 new soldiers and Hoshi´s ability should be enough to protect themselves against most of the opponents.
Furthermore, in his dialogue with Neptune Jinbei said that he and his crew went under BM´s command in order to protect themselves from the WG but that he also thinks to leave her command now and to join Luffy and co after having denied the invitation to join because of his duty towards his crew mates. Therefore, he should be on his way to the BM´s hideout right now. Since Luffy´s clash with BM seems inevitable at this point, i think the chance is high that Luffy and Jinbe will meet there and fight against BM together. What happens after the fight is of course something unpredictable at this point. Although he made the promise to Luffy that he would join after having dealt with his duty, it could still very well happen that he will stay with his crew. I, personally think that he will be hesitant to leave his crew behind but will ultimately be persuaded by Alladin and co. to free himself of the shackles of the past and just have fun with his newfound friends.
Lastly, a nomination for NN without any basis: I really like Bonney for the SH crew. Her personality + her powers definitely are unique enough, she also has at least a particular attitude towards the SH(especially Zoro) and she seems to have a connection to either Ace or WB. Her crew having been destroyed by BB also helps of course.
