But still, make a clone with no memories or history that stays in-suit/concealed, etc. Shift the replacement to someone slightly similar each time, and in a few years, they should be free of trying to match that hard.
Unless they're open about other rangers deaths, the suits seem to hide it fairly well, and even if the story is "passing the mantel" they can do that with the concealed clone a few years later. There doesn't seem to be any special reason to only force Red to be biologically the same forever.
