No, because the reason Quinx can eat human food is that their Rc level is under 1000. If it exceeds 1000, like Urie's did, they can no longer eat normal food.

Natural One-Eyed Ghouls, probably as a result of hybrid-vigor, probably have a subtly different digestion. Ghouls can't eat human food because of the enyzm they need to digest Rc tissue, in other words humans and other ghouls. Perhaps this enzym slightly mutates in the case of a born One-Eyed Ghoul, allowing them to digest human food, in addition to inheriting a more human-like tongue. Ichika's birth confirmed that all natural One-Eyed Ghouls can eat and digest human food, as Mutsuki sent Ichika apples, and Touka says "Our girl loves fruit".
