LMS launch for HTML5

So we have a number of older published files (with HTML5 and Flash).  The Story.html launch file has been incorrectly reading the environment and trying to run Flash when support is removed.  Until we can locate and republish all of these courses:  Does anyone know if we could fool the LMS (Success Factors) by deleting exiting Story.html launch file and renaming index_lms_html5.html to Story.html?  Bypass the Flash checking altogether.  Thanks for any suggestions.
