We want to design the widgets page in the admin panel a little differently, mainly in order to help the site administrator understand where each widget will appear in the site:
For that, we need to change the HTML that widgets.php renders (simply changing the css isn’t enough). How would we go about doing that without touching the core?

If you upgrade your WordPress to 3.3.1, which you absolutely should, each widget area in the admin now has an ID you can use to target via CSS, which really should be enough. See http://core.trac.wordpress.org/ticket/18334 for an example.
