Widebody wheels lil devil fenders

Curious if I could get away with running rears of a wide body to give the car a staggered look. Ive got the FR 70 wheels that fit the 275’s and recently noticed that the wide body wheels also come in the same design. What y’all think?

I'm in pre-purchase mode and wondering if the fender flares of the widebody trim actually are necessary for running wider rims / wheels than the stock narrow body. I see that the widebody benefits substantially from the additional surface contact, but the fender flares appear to be cosmetic...
