Just occured to me that I could put one transducer inside the other, 
something like this:

(transduce list-fold
           (map (lambda (x)
                  (transduce vector-fold
                             (map (cute * x <>))
                             collect-list
                             vec)))
           collect-concat-list)

Assuming collect-concat-list concatenates the resulting list-of-lists. 
It's not as pretty but doable.
