I like this idea, though I am quite a newbie when it comes to trails.

If the markup becomes page variables, is it possible to do "things" to them?

I was thinking my my truncation mod could become something like: 
left({TrailPage$Prev},20)
(although I would be quite happy with a config.php setting)

Or you might be able to test things like:
(:if !exists {TrailPage$Prev}:) This is the first page on the 
[[TrailPage]] path through this wiki ....  (:if end:)
