I am sure that the thought "if only someone would make new sids" crossed the minds of many of us. But to be honest to get a hold of the mask would be quite an achievement on it's own. Then having them produced in a fab at reasonable costs, well that would be nearly impossible. The market for sid chips isn't big, only us idiots are willing to buy them. And with releasing a couple of thousand chips on the market, prices would pummel.
