Change method of rewrite-redirect?

I have been rewriting my urls a certain way and now want to change them to include some keywords in the url.

Is there a way to redirect one rewrite style to another with a 301?

 

Post example of current URLs, and how you want them, and the original URL. I think you'll get the infinite loop.

 

I'm trying to possibly

redirect this

http://www.xxxxxxxxxxxx.com/cp-app/prod/sports-memorabilia/HM-NYMPRIDEK

RewriteRule ^cp-app/([^/]*)/sports-memorabilia/([^/]*)/?$ shop/cgi-bin/cp-app.cgi?pg=$1&sports-memorabilia&ref=$2 [L]

to this

http://www.xxxxxxxxxxxx.com/sports-...-Mets-Team-Pride-Photomint--HM-NYMPRIDEK.html

RewriteRule ^sports-memorabilia-(.*)\.html shop/cgi-bin/cp-app.cgi?seo=item--$1

 

I don't think it'll work.
