I wrote on this early about myself having hip replace in may of 2015, and after reading your posts I'm thinking what the hell are you thinking? You have had major surgery, this isn't just about skiing again this about walking when you are older. You need to look after yourself and not screw this up. if you EVER want to ski again take the time and let your body heal, don't do something stupid. My Physio told me about a patient that she had who surfed, and he went out after 4 weeks after hip replacement, dislocated it really bad and never surfed again and can hardly walk. Don't be an idiot use your head.
