I'm not entirely sure this will be a problem, I do like the idea of a huge ring/cog setup on a huge bike, but I'm just pointing out that you're going to run into some unexpected problems. You probably won't have chainstay clearance issues since you're going outboard a little and it's a track frame, but you might. You also only really have one option for changing a component to mess with gearing, but that's not a huge deal with SS as it's not like you have to worry about skid patches.
