I see where you coming from.
But when i look at them, they dont fit that much.
Starting with Queen, he is pretty much hated by Kid and Killer, there is no way they will forgive him and trust him. Also they dont need 2 mechanics.
Jack is a wild beast, which fits characterwise into that crew and would be the most plausible. But there is just not enough to know about him. He kinda feels displaced in my opinion. But maybe that changes.
And King, i can see him fitting just cause Big Mum wants him in her crew. But at the end, he seem to loyal to Kaido and is sticking around Kaido for such a long time. Maybe when we know more about him.
With P1 and Ulti. They are just rumbling siblings, kinda Kids, annoying, loud, fighting over and full mouthed. I can see that "Kid Pirates" Version of an Idiot-Trio with them so good. Just imagine P1 and Ulti fighting over something, Kid tells them to shut up and they come into a 3 man rumbling, with Killer annoyd at the side. Also with Ulti he would have a rivalery to Nami, with P1 to Sanji. It would come to:
Luffy - Kid
Zoro - Killer
Franky - Heat
Jinbei - Wire
Sanji - P1
Nami - Ulti
...
In my point of view, it kinda fits.
