Really? I think she would raise disciplined, albeit competitve with each other, kids. She would make them respect her and even sometimes fear her, but she would care for their upbringing and potential.
Whether or not she would love them, it depends on how she is reformed.
If she managed to find a honest and true man who would be willing to love her for who she is and make her open and share her past pains, he would be the only man in her life who truly loved her (maybe other than Zuko), we could see an Azula who finally can feel love about someone other than herself and the idea of "perfection" that was instilled on her from a very young age. An Azula that can give love.
