Kinda reminds me of what its already like in X-COM. I did notice it took x amount of TUs to go up an incline one step as opposed to moving on flat terrain one step. So I think that game had it, though after so many experiments to see what's what, eventually one could actually do some predicting, but I like what your saying.
Just some stuff I noticed off the top of my head playing recently...
On flat terrain for example, if I had 4 TU left, I could move one full square spending all of it. However, if the terrain is "flatish" but there's a patch of tall grass in front, he won't move at all (I suspect it took 1-3 TU more to move to that square than normal) My men were modestly loaded out so I haven't done any movement experiments under more weight.
I think what should be unpredictable is whether they slide/slip/run in place (no traction heh)/ or fall.
