About This File
I made a very similar mod to this a long time ago, but it seems it disappeared with PCGM and I no longer seem to have a copy.
What it does is swap around the default flourish/stances used for melée weapons - the single blade flourish is replaced with the stun baton flourish and vice versa, the Echani-style flourish replaces the two melée weapon flourish and vice versa, and the double-blade flourish is replaced by the "Natural Attack" (or "Rocky Mode" 
) flourish...Just look at the screenshot for details.
