[The Bladesman]

I gotta disagree with the notion that Power rangers shouldn't have continuity between series, that's what makes it stand out from sentai (or at least did). If i were to re-write the disney era, I'd strengthen contiunity between series nothing crazy but at least have some major events from each show be mentioned from time to time like how lost galaxy did it. Secondly I'd try not to cut out any zord footage, jungle fury was truly guilty of that it seemed like it only kept it because it had to. I'd also not end series with the rangers losing or sacreficing their powers, I think its kinda a waste of story potential (but then again I'd like to see rangers fighting normal crime as well). Beyond that I'd use the sentai movie footage as well some of that stuff is pure gold (Gaoranger vs huricanger has got to have some of the best ranger team fights I've ever seen. the opening mecha fight in Abaranger vs hurricanger would have worked so well in the power ranger crossover).

Ninja storm: Yeah cyber cam is painful but I'd keep Lothar, It wouldn't be hard to make him a legitimate villain just transplant some of his comedic elements onto some of the side villains.

Dino thunder: I'd probably try to tidy up the story a bit. I'd focus more on the main cast and a bit less on side characters. Wasn't there a throwaway line where trent said his twin brother flunked out the ninja storm academy, I might do something involving his brother.

SPD: It was an old fan theory but I'd include the blue centurion as the founder SPD, it doens't need to be anything major just a cameo here and there.

Operation overdrive/mystic force: Both shows have a great deal of wasted potential to be honest I'm not sure what i would do beyond replace some of cast for both, giving mystic force a spd crossover episode and like dino thunder spreading the focus onto the main cast. If I wanted to be daring I might keep operation overdrive's various villain factions around till the end and have the series conclude with the actual cross over as for the villain i'd remove thrax and either use a time traveling lord zedd or maybe some kind of composite being from all the evil destroyed by the z-wave but that might be a bit over the top.
