If you're not intent on making it innately solo-friendly (considering most characters probably can't carry out more than a few gold bars at a time), I would suggest a 2-or-3-Rank Talent that reduces weight of Gold Bars by SR*2 (or 1.5, rounded up to the nearest whole number for added incentive at SR3 if it becomes a 3-Rank Talent, alternatively).
