There is MassRename that you can use to rename multiple pages. The syntax for its input is the following: Old_title_1 New_title_1 Old_title_2 New_title_2 Old_title_3 New_title_3 Old_title_etc. New_title_etc. So you should first get the full list of pages that you want to rename, format them with underscores instead of spaces and duplicate each on the same line with the new format.

Could you perhaps post here this list? Perhaps i could format that for you so you can instantly use it. And is the only rule "~ X" -> "~ X Costume"?
