That's still a lot of iron hanging out front.

True but the mount could be greatly simplfied by using
the schertz beam concept. The CG of the gearbox-engine-prop combo
will be near where the bell housing bolts to the engine. Just like
the rotary.

The cost of the motor mount is directly a function of the number
of joints that need to be trimmed and  welded.
