Calling All Script Geeks

Hear Ye, Hear Ye: Google Kings, Script Geeks, and Internet Gurus, I call on thee:

I’m looking for a script that will take 8-10 RSS feeds, cull them down to the 5 most recent items in the feed, and combine them into a single feed.

Does such a script exist? Let me know. I just banged my head on the desk for the 318th time. I think I dented it (the desk), so please let me hear from you soon.

Thank you.
