Yes, there is a lot a experimentation that can be done on this subject. Comparing the higher static thrust engine using static augmentation against the set up which is optimised for thrust maintenance at hgher speeds is similar to comparing props vs jets. The prop accelerating a higher mass of air at lower velocity and vica verca for the jet, it's a simple thrust = mass x velocity equation......the engine optimised for higher exhaust velocity continues to maintain this side of the eqation at high speeds and so continues to impart thrust to the airframe.

I have a static thrust augmenting pipe in my Eurosport because the airframe is designed for the low-medium speed flight regime where thee pipes have best effect.

I think it would be interesting to experiment with a variable geometry nozzle more inline with fullsize practice.
