Short of buying a replacement set from Das (not sure if they do that), not really. You can try to get a group buy going for PBT keys from SP. With enough people you'd be looking at $70-$90 a set I believe. WASD Keyboards will do custom etching and engraving for a fee. I think their sets are $40 or $50, plus $10 for the custom legends. But they won't look very good TBH.
