I have editted the CharactersViewer.lua SkinMe skin so it now actually skins the latest (and also last ever) version of CharactersViewer 2.89.
Also I changed the last line
for i = 7, 12 doto
for i = 7, 13 doso it now also skins the last bag in CharactersViewer if you have all bag slots filled in your bank.
I'll attach a copy of this file.
Hope you can implement this in your Skinner addon which I'm stillusing with much fun :)
