RSS feed for a custom page template

I would like to know if it is possible to have a custom feed based on a page template and how?

This is my custom query:

$my_custom_query = new WP_Query( array('cat' = array (4335, 12488),
    'posts_type' = 'post',
    'showposts' = 35,
    'paged' = $paged,
    'meta_key' = 'views', 
    'orderby'= 'meta_value',
    'order' = 'desc',
    //'orderby' = 'desc',
    // BOF EXCLUDES POSTS YOUNGER THEN TODAY -30 DAYS *  
    'date_query' = array(
    'column' = 'post_date',
    //'after' = '2010-01-01',
    //'before' = date('Y-m-d', strtotime('-30 days')) 
    ),
    // EOF EXCLUDES POSTS YOUNGER THEN TODAY -30 DAYS 
    //'offset' = '21',
    'post__not_in' = get_option( 'sticky_posts' ),
    'meta_query' = array('0' = array('key' = 'videos_na', 'value' = 'true', 'compare' = 'NOT EXISTS'),
    array('key' = 'master_id', 'value' = 'true', 'compare' = 'NOT EXISTS'),
    array('key' = 'old_id', 'value' = 'true', 'compare' = 'NOT EXISTS'),
   )));
