I have seen such slides from the outside, when there is a misunderstanding, in which TKAS intervenes, and there such slides are quite possible ... But this is an extremely rare case, its probability is very small.
The situation in which the liner will have to make such maneuvers is almost impossible. Plus, they are not designed for their implementation and you should take into account the commercial load (passengers, luggage, mail, cargo).
But many companies offer you either to experience various maneuvers on light sports aircraft.
Also, as far as I know, tourists in Russia are offered to experience several sessions of weightlessness on a special plane. It comes just when the slide is performed.
Perhaps the most famous tourist to me who has experienced such a service on himself is Stephen Hawking.
