“Remember why the Sith are more powerful than the Jedi, Sidious: because we are not afraid to feel. We embrace the spectrum of emotions, from the heights of transcendent joy to the depths of hatred and despair. Fearless, we welcome whatever paths the dark side sets us on, and whatever destiny it lays out for us.” ― James Luceno, Darth Plagueis
Regarding clones, an army of female or mixed clones to counterbalance the clones of the republics can be interesting. (As a person's gender is defined by genes, making this change should not be difficult; aside from avoiding thought alterations to make them more docile, an army of ARC troopers may be of interest.) The best army for my taste would be a mixed droid/human weapon with droids like Skytroopers or Sentinel droids as normal units and clones to lead them at the head of each unit.
