We have an analog of such elastic joint already - SD1 spur damper.
But any elastic joint doesn't remove the transfer of the torque from transmission to the chassis.
It only dampens the torque oscillations but doesn't affect on the average torque transfer.
FFG removes the transfer of the torque to the chassis completely (actually zero transfer).
