I think it would’ve been a better resolution for Dukat to genuinely see the error of his ways and have him end his story in a similar way to Garak, only have him do it on Bajor.

It’d be really satisfying if after all his atrocities and delusions of grandeur he chose to live his life in relative anonymity helping the people he’d oppressed in a humble way.

I think it would work if he ended up turning himself in for trial and most-likely execution. I don’t think there’d be any route to forgiveness for him.
