The "electronics" from either the F27 or the Cub can be used, but the F27 will need the jumper changes for a conventional tail. By "electronics" I mean transmitter, receiver/controller and servos. However, neither motor drive will work. The F27 is set up as a pusher: you would need to reverse the motor and if you already used the motor as a pusher, the brushes may become damaged if you reverse the motor. The Cub's motor and drive are designed to keep the very light (15oz) Cub in the air, but without much extra power. Your plane, with all of the electronics and motor, will be twice that weight. You will need a considerably more powerful motor/drive and larger battery than the Cub's. You probably need to consider the powerplant from the PZ Mustang for this plane.
