Have ToQ-Oh, Grand Liner, Travelion, and Kyouretsu-O merge into one big mecha in the movie. This crossover idea can also work in America since GoGo V, Magiranger and Go-Ornger got adapted into Power Ragners amusing that ToQger does not get skip over it.

Having the Ancient Engines and Travelion appear would be amazing. But I don't think they'll do a big crossover like in Kyoryu vs. Go-Bus again.
