How to build HD 149026b with its massive core

Discovering the Growth Histories of Exoplanets: The Saturn Analog HD 149026b

Seems that the way to build the Saturn-mass planet HD 149026b is to start the planet at roughly Saturn's distance from the star and have it migrate inwards through a disc with roughly 2 times the amount of solids as the solar nebula had. This results in the formation of the planet's massive core as it migrates.
