@Omkar_Phadtare - I don't think it is a good practise to move the default workspace of XF or Forms. In case of AEM Screens, most likely changing the workspace from /content/screens to something else won't work because AEM channels are coupled with screen player (application) and there would be paths which would be preconfigured within the player app which will result in content not showing on the Screens.
There could be some default allowedTemplates on those workspace paths as well along with some other linking which could break the normal functionality.
May I know what is the use case for this ask?
