I mean, that's the idea. I haven't researched if it's a) possible or b) would result in useful gearing.
A Surly Dingle cog in 17x21 with a 49-45 would work. The 49-17 makes 76 GI and the 45-21 makes 57 GI.
A Surly Dingle cog and lock ring is about $65 and I have found a 17-21 freewheel for $40 on ebay
