Ford, Fokker, Junkers, Ansaldo-Balila, whatever, it doesn't matter.

One running engine in the center with dumies outboard, you have, and are flying, a single engined plane, with all the advantages and disadvantages that pertain. And it would fly better if you left the props off the dummies - less drag.

One engine and two dummies?
. Should be buried with the mummies.
