The only way I could see this done effectively would be in plastic with the common platform, and done with its companions done for other roads. The ATSF units fell into an EMC category of 1800HP "B-B" diesel-electrics all done around the same time. It LOOKS from the design and size that they were the predecessors to the E unit passenger diesels and also had dual engines in each unit. The units had cabs at both ends. I believe CB&Q also had one with a single-cab to pull one of the Zephyrs. See https://en.wikipedia.org/wiki/EMC_1800_hp_B-B for the full article.

Baltimore and Ohio
The one in question for ATSF. Note that though they seemed to travel as a pair they were also double-ended.
