Mergers of `Cuspy' Galaxies

Galactic spheroids have density profiles scaling as r-1 or r-2 at small radii. Can bright spheroids, which have shallow profiles, be assembled from faint spheroids, which have steep profiles? How does the profile influence the merging process and the remnant's distribution function and radial structure?
