There are a few complications with installing suicide doors, or reverse hinge.
If you drive a small car, you might have to move your fuel door to accomadate the hinges. Take a good look at the front hinges. You could probably get away with a set of smaller hinges if you have nothing on the door, or your doors are small and light.
It's a problem for sedans because of the wheel arches. There is only a small straight area where the hinge can be mounted, typically right above the arches. So you would probably have to make sure that your whole door can be supported by just 1 mounting pointing. It's infinitely easier if you are planning to do it on a coupe. This is because of the larger area, and all you have to do is migrate all the hinges to the other side.
Wiring also poses a challenge if you are planning to reverse hinge a sedan rear door.
Also, suicide doors nowadays don't open 180 degrees. They open more like normal doors. 180 degrees operation is possible, but you would also need to hinge the door as well as the body. A lot of trial and error.
