Stacking images should give you at least as good noise performance in the shadows as bracketing.

If you only stack (instead of bracketing), won't your shadows potentially take multiple "hits" from pattern noise, black clipping (if your camera does it), etc.?

Yes, that is a good point, and it's worth testing how much this adding up of "per-shot noise" will mean for the final image. There might very well be a break-even point. For the E-M5 the sensor noise is fairly low, so I would suppose that the perceived noise (signal to noise ratio) in the end image would still be lower, even with multiple exposures, because the read noise is fairly small compared to the shot noise caused by (lack of) exposure.
