Default crzy idea..

I've been eyeballing it for a month or two now... The idea of a multiple geared engine.. I always see multispeed bikes on eBay, and I was wondering if anyone out there has thought of the possibility of engineering a left side mounted shimano type derailleur... Ideally a 3 speed, one large low speed gear with big torque (like 60+ teeth) then the standard 36-44 tooth, then a small tooth for top speed (like 27 teeth).. I think the biggest trick would be making a chain guard to enclose the drive chain should it slip,break, and go flying..

is this possible? any thoughts?
