Hello Greg,
Right now the skin would be replaced but here is a way to have them booth:
1 - Open on SkinStudio, the skin you already have installed.
2 - Click "File > Save As..." and Enter a new name you want and click "OK" (will take some seconds)
3 - Now that you have the skin with a new name, go ahead and install the other skin.
I'll talk to the WB developer and suggest a feature that would ask the user to "Replace" or "Rename"
skins with the same name.
Regards.
