I did it! :)
It was so much simpler. I created a function
group-to-alist/vector, based on the previous function, to which I added
the map I was already using on the controller.scm for data-groups.

(define (group-to-alist/vector process lst)
  (map
   (match-lambda
     ((label args ...)
      `(,label . ,(list->vector args))))
   (group-to-alist process lst)))

The only change needed on the html.scm is to use vector->list in the
items, like this

(map
 (lambda (alist)
   ...
 (or (vector->list items) '()))

Please, tell me what you think is the best, this way or the other that
I sent earlier with the patch?
