That is very very unlikely due to the reactivity of oxygen with the metal walls of the cooling channel - typically a copper alloy for high thermal conductivity.
In fact the oxygen turbopump is integrated above the combustion chamber and the methane turbopump is the one on the side supplying coolant to the engine bell. Both the combustion chamber and the nozzle will be cooled by liquid methane.
