If there are zeo crystals, I can see my explanation work best. Even looking at the coins, they're not even solid metal anymore, and in the show they'd use to be able to extend. I feel though that if they get the Zeo Powers out of the gate, unless this is an evil team, then they're too powerful and the movie series will get boring quick.
At least M.Night isn't handling this. Though personally, Landis's script and Michael Bay's direction [alongside whoever designed the Dinobots] would be probably an okay movie, while it felt scant on a few details and lacking in its setup, Zack being the Pink Ranger and Kimberly being vice versa was an interesting idea. It was basically MMPR actually.
I don't think we'll ever see Zeo powers even if the they do use the crystals. I think it would just be a repurposed plot device.
I read only a crumb of Landis' script. Idk some of it seemed alright, I vaguely remember hearing about the color swap. That is kind of cool.
