I'm in the same boat as you with the SSD issue and I think I just thought of a solution. Download a Symbolic Link creator (I've always used Link Shell Extension).

1) Move your CoDWaW mods folder to a different drive.
2) Right click the mods folder on the new drive and choose Pick Link Source
3) Go back to the original mods folder location in AppData and choose Drop As -> Symbolic Link.

That should make the game think the folder is there, even though its actually being redirected to your other drive by the filesystem.
