Renaming the Documents('Divinity Original Sin') directory and moving the saves to the newly created profile did the trick.
I tried moving just the new LevelCache to the old directory but it didn't work. So, I replaced the old LevelCache as well as the [config.lsx] and [modsettings.lsx] files. And it works. The old directory is restored via the new Cache and those two files.
Thanks again for the help! I was concerned I'd break something else if I had tried to do it without your suggestion. Was contemplating re-installing. But this was so much less time consuming.
