As vickster said, just strip it of anything practical and useful. If you're dead set on following fashion then just remove the granny ring and set the stop screws to limit the front mechs travel.
Reversing the headset spacers and /or fitting an adjustable stem will allow you to slam the bars for that aero backbreaking position. Doing so might limit the amount of cable pull if cantilever brakes are fitted though.
As a touring bike, I'd imagine you'll be limited to going as narrow as 28mm tyres, although why anyone in their right mind would deliberately fit narrower harsher tyres is beyond me.
Just one more thing, if your tourer has the same tyre and mudguard clearances as my Vantage, without the mudguards it'll look completely ridiculous. Butt ugly in fact. Just my opinion.
