[Den-O]

I've imagined for quite a while that Saban should do a mashup of Goseiger and Gokaiger for a new series. The Pirate Rangers could be on the run from an empire that has subdued and destroyed all previous ranger teams, scattering their powers. The Goseigers (Knight Rangers) could be a group of naive rangers who work for the empire and don't realize they're doing evil. Gosei Knight could be The Black Knight that has to come after the Goseigers once they switch and side with the pirates. Throughout the series the pirates, who've chosen to hide out on Earth, progressively meet their predecessors and continue receiving new Ranger Keys. In the end we could have an awesome finale where the Pirate and Knight Rangers help stage a huge revolution against the empire and the Knights could die in the battle leaving the Pirates to avenge them and defeat the corrupt emperor.
