PR episodes are rarely straight translations of Sentai episodes. Plus there are usually only about 30 PR episodes in the series compared to about 50 Sentai, so Saban wouldn't have to use any of the Pre-Zyuranger footage at all. They'd likely just keep the Zyu and later stuff and work around that.
I'm curious though if they'd comment on the Yellow Rangers with skirts. It's been kinda cool seeing the skirts added to the uniforms that probably should have had skirts, but didn't, because the original Sentai version was male...
Yeah, I highly doubt that Saban would use the suits from Goranger to Jetman, as well as doubting them using the 5 Dairanger suits.
Plus the male actors that played as Ki Ranger, Denji Yellow, Vul Panther, Goggle Yellow, Dyna Yellow, Yellow Lion, Yellow Turbo, Yellow Owl, Tiger Ranger, Kirin Ranger, Ninja Yellow, Ginga Yellow, Go Yellow, Time Yellow, Gao Yellow, Hurricane Yellow, & Magi Yellow were the true, actual yellow sentai members, as the actresses that played as Blue Dolphin, Blue Swallow, Hurricane Blue, & Magi Blue are the true, actual Blues.
Same with Big One & GekiChopper being true, actual male sentai senshi extras.
Joe, Ahim, & Luka are just imitating their styles when transforming into them.
