Denying Creeps and Death Penalties

Is there a chance we will ever see a patch upgrade that allows us to deny creeps? Or maybe one that establishes a gold loss formula for dying? I ask because I've found that these are the kinds of things that can help balance a game. For instance, if that snowball Riven top lane stays in her lane a bit too long trying to farm for a big item, it would push for the opposing team to prioritize a gank and cause her to lose a good amount of that gold, whereas in the current format, most players will just avoid ganking a snowballing lane. And as far as creep denies go, I feel as though, every level of gameplay, all the way up to the pro level, would benefit highly from being able to deny creeps and here's why: for a tough lane matchup (melee against ranged) you can't always get up to the enemy creeps to try to maintain even farm against an aggressive enemy. But you can reach your own creeps usually, and well timed denies would prevent your opponent from getting that farm, thus balancing the lane farm. Thoughts?
