To change the order of the cogs you MUST have a cassette, opposed to a freewheel. I assume you do? Then you'll need to separate the main cluster, probably by filing down the rivet holding them all together, and nocking it out with a hammer. You can, in theory, arrange the cogs in any order you want. However, I think the smallest cog must stay at the outside edge due to it's shape, and the way it fits on. Not sure about this though? If you don't plan on using the biggest cog (gear 1), then take it off and put a spacer there instead. That would look better than having some crazy arrangement of gears.
And you could just leave your FD on the bike, locked out over the cog your using at the front (taking the cable and shifter off). It would help keep the chain on.
