Here are some more of the rumors of Kikai Sentai Zenkaiger from various sources:
1) The suit designs are based on Mechanical or Ultimate forms that are similar to the following Super Sentai Series like for instance, AbareMax of AbaRanger, DekaRanger SWAT Mode of DekaRanger, Super Goseigers of Goseiger, Go-Busters Powered Custom of Go-Busters, KyoryuRed Carnival of Kyoryuger, Hyper ToQ 1gou/Hyper ToQgers of ToQger, Akaninger Chouzetsu of Ninninger, Super LupinRed/Super LupinRangers and Super Patren 1gou/Super PatRangers of LupinRanger Vs. PatRanger, Max RyusoulRed/Max Ryusoulgers of Ryusoulger and more recently, GoKiramagers of Kiramager.
2) The transformation/henshin device would probably called Zenkai Scan, a medical thermometer designed scanner with Zenkaiger/Zenkai Keys. The keys are similar to that of Gokaiger's Ranger Keys, but in different forms.
3) The starting line-ups or the core five would be either ZenkaiRed (Male), ZenkaiBlue (Male), ZenkaiGreen (Male) ZenkaiBlack (Female) and ZenkaiYellow (Female) or ZenkaiRed (Male), ZenkaiBlack (Male), ZenkaiBlue (Male), ZenkaiGreen (Female) and ZenkaiYellow (Female). Who knew that the first Black Sentai Heroine could be beautiful if she wears various clothes in Black? But that's another possibility.
4) The mecha would probably called Zenkaisers, but will they transform into past mechas like Variblune of GoRanger, Bio Jets of BioMan, Guardian Beasts of ZyuRanger, 99 Machines of GoGoFive, Gougou Vehicles 1-5 of Boukenger and such?
5) The Kaizoku Sentai Gokaiger 10 Years After Movie may have a slim/big chance of returning the physical actors and actresses. This may be either a standalone movie or they'll teaming up with the Zenkaigers.
6) The fate of the Super Sentai Teams who were disappeared in the ill-fated Super Sentai Strongest Battle, but will they reappear and return to Earth alive to meet the Zenkaigers? Plus, Rita will probably escape from jail in the revenge against the Ryusoulgers for intervening the S.S.S.B., then she'll face the other Super Sentai, the Zenkaigers and AkaRed and will probably have her monster form that we never saw in the S.S.S.B..
7) AkaRed, who is now a ghost/spirit, has the number 45 on his left chest and XLV on his belt. Don't know if Touru Furuya will still be the voice of AkaRed or a new voice actor. He'll probably meet the Zenkaigers and the other Super Sentai Teams and fighting against each other or another Super Sentai Strongest Battle is avoidable.

Of course, due to COVID-19 Pandemic (or if the virus is still around next year), the rookie actors and actresses and the veteran ones must follow the strict health protocols to avoid the Rio Komiya incident last March/April this year. Good luck to them!
