Sure. But it's all about fuel. These thing gulp it down. Fueling system in the case of an SL can't be an afterthought. It must be designed into the ship, and would likely mean multiple tanks etc. Probably fuselage and wing tanks. A poorly designed fueling system can lead to all sorts of issues with turbines.

And to seque back to glider mounted jet engines... What happens if you mount two of these engines on a glider? Enough thrust for self-launching? Redundancy for sustaining (or to circle back on aborted takeoff)? Twice as many things to break? 2X the cost?
