It is a fantasy PA setting, so LL or MF would work well...certainly the option to combine both would be welcome...here are a couple of the playable races
aarakocra
dwarf
elf/eladrin
goliath
halflings
Pterran
thri-Kreen
tiefling
dray/dragon borne
I am leaning heavy towards what we can easily sell to the common D&D crowd as well as bring them into the MF style of gaming as well
