What about a merger between gatchaman with silverhawks ?

Hold the phone everyone...I just thought of this: A food-based ranger team. They're called, Gourmet Sentai Hamburgers.

YES.

What about a cat themed voltron/thundercats ripoff which each ranger representing a large cat species (lion,tiger,panther,cheetah,lynx,jaguar,bobcat,etc).

It would be cool if the 2015 Sentai is Wild Animals again. We can get a crossover between Liveman, Gaoranger, Gekiranger and 2015 Sentai.

Another Rescue Sentai!

Because if you can do Dinosaurs thrice, why not Rescue twice?

I'd rather have a fire-fighting Sentai so we can complete the Emergency Services trinity.

Oh yeah, I forgot Dekaranger.

Then again, I consider law enforcement to be separate from rescue services.

That totally reminds me I need to finish Rescue Force and make my way into Rescue Fire.
