How to replace Javascript of production website with local Javascript?

Viewed 33151

On my production website, I have compiled Javascript.

<script src="/js/mycode.min.js"></script>

It would be very convient for debugging if I could make my browser replace that with

<script src="http://localhost/js/mycode1.js"></script>
<script src="http://localhost/js/mycode2.js"></script>
...

I know I could manipulate the DOM using something like Greasemonkey userscripts, but I couldn't come up with a solution which would prevent the execution of "mycode.min.js".

Any ideas?
