Yes, there's photos of an AU-1 that was painted in a gull grey and white scheme during the sixties, I believe. There is an illustration in Francillon's Vietnam book of an F3D Skyknight with the same scheme, confirmed by the same markings on the Falcon 1/72 kit. I don't recall seeing the F4U in an Atlantic I or II scheme, but it's possible.
If you want something exotic, there are some interesting schemes for F4Us and FG-1s that participated in the 1969 Soccer War between Honduras and El Salvador.
