Views 3, Modifying RSS Output, HOW? Woud like to make "iTunes Compatible" feed

So I've been trying to go at this for a while, mostly searching the forums and other blogs for ways to do this. I see that there is an iTunes module that might work for this, but it doesn't have a drupal 7 compatible release.

I have a view, called "podcast" that has an RSS feed displaying my latest podcasts (which is it's own content type).

Is there anyway I can modify the template files to create something like an iTunes RSS feed. For example, Drupal RSS feeds still have the HTML header, so I would would to replace that w/ an XML header like below:

So here's where I am trying to get started. I thought maybe I could modify the html.tpl.php w/ something like:

views-view--podcast--rss-html.tpl.php

That didn't work, I'm not sure if I'm naming it right, or if I can even do this...

I'll also need to have access to fields, so I can wrap my "Description" field in the podcast with the XML tag.

And yes, I realize I can probably easily do this in Feedburner, I just have some other reasons I'd like to do this using the Drupal RSS...I'm not expecting a surefire answer, but hopefully with your suggestions I can figure something out.
