Never say never. Here is a shot of an NYC Baldwin RS-12 leading a GP7 trailing another RS12. Saw such combo's a lot in my youth. Unfortunately I don't remember whether a few geeps had the special equipment or whether the RS-12s were modified.

Well, I don't see any MU hoses on the long hood of the RS-12.
OK, I see it now. So would you guess the Baldwins had an auxiliary electric controls for the throttle and brake since Baldwins controls where air and pneumatic?
Assuming the Baldwins still had Baldwin 'innards'. By the time these pics were taken in the 1960's, some railroads had remotored their Baldwin engines with EMD ones. IIRC the Baldwin bodies were large enough they didn't need to extensive modifications of the hood as was required when remotoring some engines, like on some ALCO engines.
This is indeed an odd m-u feature. As Chuck pointed out, there are not the standard 4 m-u hoses on each side of the pilot that would be typical of an engine with Number 6 brake equipment and air control of sanding. Likewise, the Wabco throttle air hoses are absent. All I see is an electrical jumper receptacle and a couple of extra hoses on the pilot. Perhaps the rear end of the engine had a different air hose arrangement. And this engine was far from new when the photo was made, so it could have had its m-u connections modified by the home road shop.
