Rather than buying one Svengali deck and being stuck with a single (short) force card, if you buy a short deck, you can then get multiple one-way, two-way and three-way force decks (long), and you can then change the force card each time you use it, or have a two-way or three-way force in your Svengali.

Just change the way you present and riffle to manage the swap in which cards are long vs short.
