Possible? Yes, but you will finish much lower than where you started.

So, basically it's just because of a low-hp engine that the maneuver
can't be properly executed?

The answer is not that simple. Low horsepower engine is one, design and
strength of the airframe is another, skill of the pilot is a third,
design of the airfoils selected, design of the the control system,
design of the engine systems, etc. Many factors contribute to "how" a
maneuver can be flown.
