Rocky beat me to the suggestion: just put a Systainer under it to boost it up. If the Systainer or Sortainer wouldn't be easily accessible, there's no need to put a Sortainer there. For the longest time, I had a Sys4 on the CT-22 with the WCR on top; it was the Sys4 from the Installer's Kit if I remember correctly and I wasn't really using it. You likely have a drill Systainer not being used as I keep my drills out all the time. Before I had the WCR, there was a 'landing pad' there (which is now under the WCR to allow mounting it easily to the Sortainer) and it sat on a Sys1 for the C-12.
If you are going to sell it, you can at least give some of these ideas a try; it won't change your selling price but might change your mind on selling it. I love mine and the Sortainer idea that someone suggested here in place of the Sys4 has made it only better.
