Okay... this isn't a request so much as me wondering if such a system could actually work. I'm only posting here because if it is possible, then it's a request. If it needs to be moved, it needs to be moved.
Basically, the gist of this idea is that instead of having a ridiculous plethora of super-specific spells, 'magic' is merely the manipulation of objects around you. You would use the mouse to move events around the character such as rocks, trees, fire, et al and say, throwing them at your enemy to cause damage, or whatever.
Now, I know that there is a Mouse-Control script that allows the mouse pointer to interact with the game. And I know that collision damage is possible through a Blizz-ABS plugin.
To go into further specifics, here's what I propose:
We have a single skill, called Telekinesis, which lets you move solid objects. There might be a Pyrokinesis for fire, Aerokinesis for creating wind effects, and a Hydrokinesis for controlling water.
The hotkey for Telekinesis is pressed and held, so that whenever an object is available to be moved, you can move it. I suppose you can get better and better at Telekiniesis. A newer adept might only be able to move the smallest objects and hurl them at slower speeds, only be able to levitate them for so long or so high. I suppose there could be a skill level and the Intellegence stat that factor into these.
Could such a system be possible? If so, I'll elaborate further, or we can just discuss.
