I'm builidng my old Bottechia road bike as a winter beater/buddy bike(you know, when your buddy wants to try fixed out for size) and I had an inarresting thought. The bike has a cottered crank with a 52 and 43 ring on it. I don't want to buy a new crank set for a beater. It also has an SS wheel on it. I'm going to pull the freewheel and build it as a suicide hub. My options are to run 52X18, a gear ratio that I love, but one that a newb ain't gonna like at all. I can run it 43X16, spinny for the newb, but my Paddy wagon is geared around there, so I'd like the taller 52X18. Long story short, I want to do both; 52x18 and 43X16 on the same bike on a "suicide" hub. I'm running brakes and not skidding with bike, so I'm not much worried about the cog(s) rotafixing off. I'm going to try and use a lock ring if there is enough threading left over after two cogs and some spacers. My reasoning is that if I can get a decent chainline on either chainring with the freewheel, I should have enough room for two cogs. I'm going to run one chain with two master links to switch gear ratios.

Any thoughts? I'll be posting photos when(if) I manage to build this monstrosity. This bike was beat to death before I got it, but I like it.
