Physics Scaling

[Devyre]

Hey,

my question is a bit of an odd one. Is it possible to, for example, vertically scale all physics objects?
I'm trying to recreate physics of a fairly old game and one of its techniques was to scale the physics to 0.65 on the up axis to allow an easier movement across slopes (of any dynamic rigidbody). This sounds a bit dumb but actually works quite well with everything.

If it's not possible, i'd appreciate any idea that could point me into the correct direction (that still helps me accomplish the above 1:1).

Greetings
