I would actually think that the easy solution to have your cake (flavor) and eat it too (keep the game balance) would be to simply make the character a Wizard who didn't believe they were a Wizard.
Keep the laws of magic stuff, because hey, power corrupts. The rules work perfectly for the kinds of things you want regardless. Give yourself a really high Discipline, and a slightly lower conviction: large scale stuff isn't your thing, fine control is, and you need to be controlled enough not to accidentally set off a small thermonuclear explosion, or irradiate everyone around you while you are splitting atoms.
The only kink in the works comes in that you are going to have to make due without tech from all the Murphonic Field problems. But no worries, there is a solution to that too, if your GM is willing to play along: When your character uses The Sight, have everything they see be broken down as atomic and molecular reactions, thermodynamics and quantum physics. Who needs a microscope or particle accelerator when you can just focus and see it yourself?
I could go on, but what do you think of that idea?
