Spoiler alert!
I think jiaoqui will have the same head cannon to be feeder like boothiil to Argenti.
Jiaoqui confirmed to be blind/lost his sight, so his other sensory like touching, smelling, hearing, etc will be enhanced, that's why he's still a great chef and always Cook for other especially Moze.
Because he can't see, Moze and Feixiao will help him, in return Jiaoqui will cook for them and he probably likes something soft to hugs from his trauma in wars
2.5 SPOILERS
I can totally see it yes!
Moze wouldn't refuse a meal from Jiaoqiu either, even he's already full. And I think Moze would allow more physical touches from Jiaoqiu as well... Jiaoqiu would enjoy placing his hands on Moze's softening belly.
Moze wouldn't be oblivious to his weight gain, but he would deny that he's letting Jiaoqiu fatten him up
