The short answer is no. As I have suggested on this blog several times in the past, your best bet would be to make a few so-called conversion cars so that one type of coupler was on one end and the other type would be on the other. For example, you could have a box car that has a knuckle type coupler at one end and one of the cheaper single piece coupler types (Rapido in N scale or the X2F in HO that usually come mounted on rolling stock right out of the box) on the other.

Some conversions are easier than others, particularly if the coupler is mounted on the truck itself. This is called a Talgo style truck. All you have to do is to substitute a Talgo truck that has the coupler type you want.

Body mounted couplers can be difficult to change out since some cutting or drilling of the car’s body could be involved. It really depends on the type & scale of coupler you’re changing to.

Hope this helps.
