Bypass "Machine name already in use" error, re-use existing field

Currently, this module does not handle the use case of wanting to convert an image field to media on a content type when the same image field has already been converted to media on a different content type. Because this module eseentially does two things (creates the media field and then converts the images to media entities) it should first check to see if the machine name already exists, and instead of returning the standard "The machine-readable name is already in use. It must be unique." it should confirm with the user that they would like to use this existing field and then proceed to create the media entities.
