IMHO these ideas have merit, implementation either by rules, or hardwiring (Not sure if that would feasible) is the problem. The other thing that comes to mind is what kind of slope does it have to be before the reverse slope is a problem?
As far as the "shorties" go, with the new arty routines getting those guns more forward maybe a more effective way to utilize them, especially against mobile forces. If I'm not mistaken this was how they used at certain times anyway.
