See, one of the key differences to me between the moral framework in Star Wars and Star Trek is good and evil exist as real, absolute things in Star Wars. People can be good, or bad. People can instantaneously flip from being a good person to a bad one due to just one bad action - provided it's bad enough. Similarly, people can find "grace" (like Vader) after a life of wickedness with just one act.
In contrast, the moral framework of the Trekverse to a certain extent relativist. Even where it's not, it's based upon the actions that someone takes, not what is in their heart.
Considering the absence of good and evil as meaning anything other than a humanist framework, who would even grant redemption? Basically, the character themselves. That's what we see with Damar in DS9, who as I noted got the best redemption arc in all of Star Trek. He was a man who was disgusted in what he had become, and ultimately chose a new and more difficult path not because he was condemned for it, but because he couldn't stand to look in the mirror at himself. He never found true inner peace, even at the end, but he made an effort, which allowed us to have more conflicted feelings about him as a character than watching someone like Weyoun get casually shanked by Garak.
I simply don't see how a redemption arc for MU Georgiou will work, because she's safely away from the MU and never has to see the ramifications of her own past actions. More likely she'll just "turn over a new leaf" and try and rationalize that all that stuff was in the past, in a different universe, and has no bearing on who she is today. Which is a pretty weak narrative.
