6k full frame and Atem mini extreme iso

Hey!
My boss just purchased some of the bmpcc6k ff in the sale. I want to use them in our current stream lineup, but because theres no 16x9 recording option (unless its megacropped 1080) i have to deal with black bars. Our current workflow is a few bmpcc4ks and a komodo into an atem mini iso extreme (hdmi) fed into obs via decklink. Is there a way i can output from the 6kff in an uncropped 6 or 4k 16X9, or should i just make all the other cameras DCI and adjust the resolution in OBS to get rid of the bars? Thank you for any input on this.
