(This would mean that the inner templates would execute with the ??? parameter, returning something that would allow the outer template to modify the ???, then the outer template would call back the inner templates with the modified parameter, before the outer template finally does it's own thing with the result. I don't know whether or not this could be hacked.)

Maybe I’m misunderstanding but you can pass template
parameters as arguments to nested templates. As in,

/Page
{{aha|output=hello}}

/Tempate:aha
{{echo|{{{output}}}}}

/Template:echo
{{{1}}}

The content of page will be “hello”. I used a named parameter
so that the example is clearer; that isn’t necessary.

Hope it helps.
