I think that there must be some collection somewhere of templates used in spam. Sometimes I'll get the same messages that I got months and months ago that appear to be sent from a different person... maybe one of them was addressed to %FNAME %LNAME and from "eBay customer support," and another came from the "Word1 X. Word2" (as in Malarkey E. Silverback) format that's so popular right now.
Someone should start spamtemplates.com, your one-stop source for pre-made spam templates. The domain is still available. I mean, Office has the same thing for documents and PowerPoint templates already; it seems natural that someone might want a website where they can get free, professionally-designed spam templates. Maybe it would even improve the quality of the spam we receive.
