Odd question, can I add a directory to the folder structure without messing any code up?

I’d like to add a directory at the same folder level as sites, themes etc to host a few images. The reason I don’t want to put the images in sitesdefaultfiles is because we’re doing some major drupal overhauls and I don’t want the images to go down during that process. Will adding a folder named something like “custom_images” here mess anything up? Thanks!

Edit: Moved to Post Installation forum upon request!
