Change bundle from WebGL to standalone,is it posible to rebundle a WebGL exported project into standalone

I have a project which I originally exported for WebGL, so I have all the exported assets (mainly .unityweb file) in my web server. Now I'd like to have this as a standalone project, so that we don't need a browser to run it, but unfortunately, I lost the source of the project, so I acan't reexport it as standalone. Is there any way I can achieve what I need with the old export I have for WebGL?,I have a project which I originally exported for WebGL, so I have all the exported assets (mainly .unityweb file) in my web server.
