With all the great work done by Chuck I and others, I would think it shouldn't be to difficult.
For the N52 equipped Z4's I really don't think there's a cheaper option than something like the Sprint Booster or BMS Powerbox. Both are around $300 and both provide multiple levels of throttle sensitivity including the "always on" folks have been asking for. Alternatively, ECU reflashes that affect throttle sensitivity, among other things, are now becoming more commonly available for the N52.

The one thing these don't affect is the steering response. I suspect someone would have to hack around with our electric steering systems to access this aspect of the sport button as well.
