I would love this system. This is one of the reasons why I prefered magic of Daggerfall and Morrowind to Oblivion and Skyrim. One example - If you ever played Morrowind, outside the village you start in, falls a mage from the sky and dies. He created a spell that boosts his jumping abilities to an insane degree and allown him to basically jump around the continent. I have actually undergone (roleplayed) a project with my own mage, that would use the game's magic system to replicate the same abilities (without editor or any other cheating). After a lot of research and tries and failures, I actually did it :D and it worked without the Death on Arrival effect. I was extermely proud of myself and I loved that the magic system actually allowed me to do this without cheating. I never got the same feeling from Oblivion or Skyrim, the magic got very limited there.
