I think from what I've gleaned from other threads that this is not 
possible with bodychecks, but I thought I'd double check:

Most of the spam that is getting through the filters now is html only 
spam with only a single part and no text/plain alternative.

I've considered simply blocking any message that has a header of 
Content-Type: text/html; which would block almost all of these, but 
sometimes I see a header of Content-Type: multipart/alternative that 
then only have a single html part (usually base64 encoded, too).

So, trapping these with procmail is trivial, but is it possible to 
block them with postfix?  That is, messages claiming to be multipart 
that only have a html part?)

will adding a header_check to reject Content-Type: text/html; to my 
setup interfere with the existing mime_header_checks?
