It really is something watching the Buran 'takeoff' versus 'liftoff'.
The answer is no. Given the same weight it should be roughly the same power needed. That is if we are calculating it from the point of rotation for a takeoff and point of initiating a go-around.
Given the same starting conditions—weight and velocity—both aircraft will have the same kinetic energy. If the takeoff / go-around is to 2,000 feet above starting condition, then the change will be the same gain in potential energy.
If they take the same time to reach that height, then it is the same power used. (Ignoring ground effect.)
The objective of the 2 engines would be to extend the glide distance for a space reentry, say if an incorrect calculation or unforeseen event caused the space glider to come short. A corrective action would need to be applied not close to the ground, but high enough to have a meaningful effect.
