A coworker of mine with much Tapesty-fu seems to have figured out a much more elegant solution today. (this issue has blocked most of the team, so we both attacked this problem simultaneously). He blogged about it here: http://blog.bolkey.com/2009/06/06/tapestry-5-recursive-tree/
The short of it is, you have to use <t:body> delegates in the tree templates, and when you declare the component, be sure to put down a delegate, go give the inner logic a chance to continue to walk the tree, and fiddle around with the before/after BodyRender methods. Also, caching was a bit of a problem until he learned to turn it off...
