I thought of adding more good traits to balance the bad ones, but there are already a few traits mods out there that do that. Additional Traits has a bunch with skill buffs that mesh nicely with the traits in PaC. Extended Traits also has a few. But I haven't patched those mods (patching is my nemesis. Lol) to prevent the good traits from generating on pawns with "incapable" traits yet.
Hope that helps!
