Hmm. If you want TAL statements and all, I suspect you'll have to do as 
Chris suggested and instantiate a full-blown page template on the fly.
I've never done that, if I were going to try I'd probably just start
looking at the code in lib/python/Products/PageTemplates.

You might be able to instantiate a PageTemplate rather than
a ZopePageTemplate, which would be somewhat lighter as it leaves
out a lot of stuff you surely don't care about (FTP support,
ZMI management tabs, etc).
