You mean the gender-swapped Gokai Changes, right? If so, then that was part of Gokaiger's thing the entire time. In the first episode alone, the Magiranger Change had Joe as a male-version of MagiBlue (without skirt) and Luka as a female-version of MagiYellow (with skirt). Don't forget the All-Pink Gokai Change in Gokaiger VS. Gavan!

Addendum there was also the Liveman episode where Joe was Blue Dolphin, the first female blue ranger, and Luka was Yellow Lion, who was a male ranger respectively. Also there was the Jetman episode.

It'll be hilarious if Captain Marvelous as KiramaiRed can scream, "Hirameking!!!", but no sketch book to illustrate. Wonder if his Red Sentai Male Junior Hero Juuru Atsuta can react or comment on this one? Unfortunately, he's going to be with Tametomo Imizu in a Mashin Sentai Kiramager Yodonna Spin-off Movie next month. After all, Juuru is a better illustrator than his Red Sentai Male Senior Hero Captain Marvelous.

The general rule of a Gokai Change is to switch to one's suit color, regardless of the gender of the original Ranger. If there is no analog to one's precise color, switch to the only other member available. In the card game episode, during the JAKQ Gokai Change, Luka became a female-version of Big One cause there was no Yellow Ranger representation in JAKQ and Big One was the only other available Ranger Key. Anytime there was a Gokai Change to a Sentai which had a Black Ranger and not a Green Ranger, Don changed to a Black Ranger. The entire series was like this!

It's essentially just "close enough" and not "exactly correct." The Rule is "Colors" or the next closest, not gender.
Meanwhile, another interesting thing I have realized is that, if the Gokaigers were to use the Zenkaiger Ranger Keys, Marvelous would become Zenkaizer, Joe Gibken would become Vroon, Ahim de Famille would become Magine, Luka Millfy would become Gaon, Gai Ikari would become Twokaizer, and, err, Don Dogoier could become Juran. Yeah, this isn't exactly perfect. But it's close enough(?), especially considering their roles.

Anyways, I was looking at the new GokaiGalleon Key and have noticed Hinges on either side. On top, I see the colors for the Five Main Gokaigers. An interesting fact about this is that it looks somewhat like the Gokaiger Symbol is on top of it. So, here are my suspicions on how it might work. First, fold down the sail. Second, you fold the Four Quarters until they resemble the Gokaiger Symbol. Thirdly, you plug it in. When in use, it would look somewhat like the "screen" of the Mobilates. I also think that if the GokaiGalleon Key is plugged into the Mobilates of the other Gokaigers, it will give a powerup on the different limb that represent where that Gokaiger's Mecha is in GokaiOh.
Though, I still hope we get more Forms for GokaiOh.

I am well aware having seen the show but regardless thank you for sharing. :lolol

I’ll just say the fact the “mode change” voice is Nabi has killed what little chance I had of buying this thing. Not a fan.

and the prophecy is fulfilled:

NEW Ranger Keys!
