Planets with alpha=2 ("mini-Neptunes") seem to be rather rare (<50% with 99% confidence). http://arxiv.org/abs/1108.5686 The work of Gaidos et al. seems to follow a different approach to come to the same conclusion: among super-Earths, “super-Mercuries” with M ~R^alpha and alpha=4 seem to dominate.

It might also be useful to target a wider window on these planets that have a higher probability of transiting. After all, the successful detection of a pair of transiting planets with interesting orbits would probably make headlines. I'm not sure about the stability of these orbits when there's high eccentricity, though. It might be better to target some of the planets in small circular orbits.
