Seems like that would work and the friction would be very small.  I think it might need a counterweight at the center to reduce vibration, if you find that the plane starts to shake itself apart.

Usually, twins have nacelles that are too short for using a direct drive with rubber. However, there is an article on Outerzone with a model that used a unique crankshaft transmission that would lend itself to thick-winged models like the Ford Trimotor. The model was the Boeing 247 - https://outerzone.co.uk/plan_details.asp?ID=11592
There is an article along with the plan. This is a shot of the transmission layout.
