I've never seen one with full cheeks. Seems like that would be pretty hard to engineer/manufacture since the loop on a full cheek is already so small. The closest I've seen was a french link full cheek gag that used traditional gag cheeks, not hooks.
At any rate, if you prefer hooks + french link and you can live with a loose ring cheek design, those are called wonder bits or beval bits. Sometimes they're also called loop ring gags. They're popular with eventers. Examples:
Also, if you wanted to pony up the money to have such a unique item, I am quite sure Jay Shuttleworth could make you one. The way he does the hooks is like Myler and pretty low profile, I'm sure they would "fit"
