This is something that I've wished for too. I recall James' words on this,
that mode should be extended to be a first-class object, like lambda
functions.

Instead of

(mode mode-name processing-rules...)

Do

(define mode-name (mode processing-rules))
(define (create-a-parameterized-mode param...)
    (mode ...) ;with usage of param...
)

(sosofo-append
    (with-mode mode-name (process-children))
    (with-mode (create-a-parametrized-mode whatever) (process-children))
)

As you pointed out, this is not in the standard or in OpenJade, but IMO
should be considered as an extension once OpenJade matures.
