If the tripod and Wimberly head works O.K., I would just leave it alone.. It gives your outfit a "personality" and is always a good conversation piece..
Wear the bumps and bruises with pride, as its a mark of a working photographer. Many many years ago, I spent to much of my time worrying about my camera equipment, and not enough time working at improving my skills as a photographer. Years went by and I realized one day that I had begun to see my equipment in a new light. I now appreciated my cameras for the photos that I could make with them, and although I try to not abuse my equipment any more than I have to, my cameras and lens have taken their share of knocks, and when I am holding them the marks they wear remind me of all the adventures we have been on together. Of course it hurts for a while, like the time my 24/105 that was at the most - 2 months old. was thrown 10 feet, landing on a concrete driveway, then rolling under a vehicle. I'm reminded of it everytime I use it. Gotta love it!
As much as I would like to leave my gear personalized I fear that rust/corrosion would set in for the Wimberley and the chance for tetanus would increase. :(
