Right now, the info section on races says that Stronghearts are just halflings that have Favored Class: Fighter and do not have the Lucky racial trait. This kind of makes them worse than Lightfoots. In PnP, I know they get an extra feat like humans at creation, but I don't think this is feasible or worth the effort to script in.
I remember reading in a source book that Strong Soul is a regional feat for Luiren (where the Stronghearts come from) and it might make a decent approximation of the "flavor" of Stronghearts as compared to Lightfoots, with the former supposedly being a bit sturdier and less slightly less nimble than the latter.
