I haven’t tried this, but wouldn’t you just edit this line in your head element (which should be in your header.php):
<link rel="alternate" type="application/rss+xml" title="<?php bloginfo('name'); ?> RSS Feed" href="<?php bloginfo('rss2_url'); ?>" />
Change title="<?php bloginfo('name'); ?> RSS Feed" to title="desiredRSSfeedTitle"
Maybe?
This is my header.php:
<meta http-equiv="Content-Type" content="text/html; charset=<?php bloginfo('charset'); ?>" />
<meta name="generator" content="WordPress <?php bloginfo('version'); ?>" /> <!-- leave this for stats please -->
<style type="text/css" media="screen">
@import url( <?php bloginfo('stylesheet_url'); ?> );
</style>
<link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="<?php bloginfo('rss2_url'); ?>" />
<link rel="alternate" type="text/xml" title="RSS .92" href="<?php bloginfo('rss_url'); ?>" />
<link rel="alternate" type="application/atom+xml" title="Atom 0.3" href="<?php bloginfo('atom_url'); ?>" />
<link rel="pingback" href="<?php bloginfo('pingback_url'); ?>" />
<?php wp_get_archives('type=monthly&format=link'); ?>
<?php //comments_popup_script(); // off by default ?>
<?php wp_head(); ?>
</head>
<body>
<div id="rap">
<div id="masthead">
<div id="pagetab">
<div class="ltab"> </div>
<?php wp_list_pages('title_li= '); ?>
<div class="rtab"> </div>
</div><!-- end PAGETAB -->
<h1><a href="<?php bloginfo('url'); ?>"><?php bloginfo('name'); ?></a></h1>
<span class="description"><?php bloginfo('description'); ?></span>
</div><!-- end MASTHEAD -->
I think you have to rename it through wp-rss.php/wp-rss2.php, look for
<channel>
<title><?php bloginfo_rss('name'); ?></title>
<link><?php bloginfo_rss('url') ?></link>
<description><?php bloginfo_rss("description")
type what you want in between the title tags. I am not 100% on this, so backup the file locally BEFORE editing.
I’ve tested that, didn’t work for me…
