Ewok movie
Jar Jar Binks:)

One could argue Clone Wars 15 min shorts were also pretty experimental

Etc

I can get hedging your bets, but like I said that kind of QA will make sure you will never have a bad movie (assuming those in charge know their shit, sorry WB) , but great movies ain't made by committee. You can still hit all the necessary character beats/plot points without having to follow a strict tonal template. Oceans 11 is a heist film, but so is Heat, and so is Quick Change (shouts to Bill Murray)
