I think the basic idea would be OK in a UK cryptic, but you'd clue the pun explicitly. You might have something like « Pasta dish at the centre of a murder mystery and a spiteful reviewer on the radio. » Though you'd really want the surface reading to come out a bit smoother (and I don't think "penne" and "pen" are pronounced exactly the same).
