Not really, you may only decompile the module (it requires some in-depth knowledge), but you will not be able to recompile its altered source code; this way you would at least know the content of the script. Talking about decompiling is sort of muted on the forum, therefore you must know that you may use decompiled stuff for your own use. If you want to use scripts from some other closed-source mod for public enjoyment, you must ask their author(s) for permission; otherwise using scripts you have decompiled without permission is a serious theft.
You may try out Tocan's suggestion to see what happens, although if there are some other related scripts to that snippet, the mod will not work properly.
