There is no Ranger Key Clones in Super Megaforce
 

I think this provides a better and fully detailed explanation for the lack of full Lightspeed Rescue, Time Force, Space, Operation Overdrive morph and just went straight to nonsensically adapt Pre-Zyuranger teams, what is the problem with those evil teams from Gokaiger and they didn't flat out adapting it even though Basco was not adapted?

there wasn't enough time with just a shortened season to use the evil clones otherwise they likely would have had the season been just a little bit longer.
