It has a mass of 2kg, and as you said two sets of carbon fiber rotors that are operating at nearly 3000 RPMs that’s more than enough to do some damage to Percy it can easily break an antenna, arm or the mast camera as well as damage other experiments. There is a very big difference between the landing shock when the rover was locked down and sensitive equipment protected and a flying lawnmower blades impacting sensitive equipment it wouldn’t surprise me it much of the rover skin is paper thin so you are potentially even at a higher risk here.
