Folder Batch Composer Name Changes

[doane2u]

Using a script when ripping CDs I used to have the folder composer names as First-Last name. In MM it doesn't make much difference because of the great search and other organization, but in file explorer I would like to have the path show Last name-First. I have a LOT of classical music in a folder: Music\_Classical\composer by first-last name\artist-tracks,etc.
Is there any way to do a batch change on all the composer names under the Classical folder to reverse them to last name-first?
