How about tpd2? If you're comfortable rewriting everything from scratch, at least you'll be working from a high performance foundation -- http://github.com/vii/teepeedee2/tree/master

Weblocks is a very good concept if you're willing to get your head round it, and work within its worldview (which is about displaying widgets rather than manually generating HTML).

Everybody uses parenscript, which is a great concept.

Both TPD2 and Weblocks rewrite your code using a continuation-passing style transformer, which makes web apps written in them harder to debug than they need to be. It also makes testing your apps or doing any kind of automated HTTP client scripting much harder than it needs to be. There's no upside to managing app state with continuations if you are able to use AJAX.
