You can keep themes files separate but it's better if you have all the files within the same theme folder. What you can do is create a subfolfer with the files of the second theme, so they won't mix.
For your second be able to work, you will need to do some changes that will break Innovation theme for future use as separate theme, unless you repair everything again before you use it.
