Remove /wp-content/themes/ for url?

Usually I use a plugin to make it easy with redirects/cloaking urls. But this time I had to use some code to add a little function to it.

So the redirects are inside an index.php in a folder. So this is an example of an url currently (I can’t move the folder to the root because it needs the wordpress theme-functions to work – I’m calling member id in the file):

https://domain.com/wp-content/themes/meow/out/01/

It works fine, but I would like the url to be like this:

https://domain.com/out/01/

Is there a way to do that?
