Actually, with the Pittman motor, it shouldn't be that hard, there is already a Legacy board and flywheel that should do the trick.  You may need a different dogbone shaft length.

John is spot on, installing the encoder board and new flywheel is not difficult.

Sometimes the new flywheel will offset to far forward of the motor causing the "dogbone" to bind or not fit between the flywheel and input shaft for the gear box. I can trim certain areas on the dog bone and couplings but most of the time the fitment is bad enough you would want to change out the dogbone.

BUT!  Instead of going through the trouble of trying to to figure out what size dogbone to replace it with a Lionel part, and fabricating one or even 3d printing one from scratch. I remove the coupling from the input shaft on the gear box side and trim the shaft down allowing more clearance for the dogbone to fit between the flywheel and gear box. (such as I do on the Class A conversions).

This is not a huge out of the way task during a conversion because I always strip the motor down to clean and lubricate it then I also strip the gear box down to remove old grease and apply fresh grease. so everything is already apart.
