We had just ordered an adaptor for our Vortex Razor 27-60/85 scope to use with our GH2 & GH3 cameras with Panasonic 20mm & 25mm lenses.
Paul does not have an off-the-shelf adapter for the 20-60 Vortex eyepiece but certainly can make you one. I did inquire about the adapter for this eyepiece when we were considering buying the older Vortex Razor 20-60/85. He suggested us to send in the eyepiece for fitting. The new Vortex 27-60 eyepiece is of better quality or quality control so no custom fitting is required.
I would suggest you to contact Paul for advices on your scope/camera/lens combination.
