8 years ago You can do 5 burst captures with 2EV difference in the settings. This will give you 5 images at -4, -2, 0, +2, +4 EVs.
If you can compile the app yourself, you can change the limit of 6 steps of 1/3 EVs to 12 at line 985, so it gives you choices to do 4EV bracketing with only 3 shots.
L Camera's exposure bracketing works by varying the shutter speed (up to the limit of the sensor, which is ~0.8 seconds on the N5), so it fits with your intended usage.
I'm need an option to make a 2-shot bracket. One normal exposure, one overexposed four f-stops by lowering the Tv. If you want to know about my usage: http://www.guillermoluijk.com/article/nonoise/index_en.htm
