If you're going to leave the derailleur as a chain tensioner, you will not want to use a fixed cog at all. You can thread a single freewheel onto the fixed side if you wish, and have two different size single freewheels available. The single freewheel on the fixed side will install over the lockring threads, which you won't need anyway.
