Building tandem,trikebent,FWD,RWS,!!

Hi. Is there any one out there with any thoughts or ideas about my waky project. I want to build a recumbunt trike tandem(2 wheels front 1 back) In moments of clarity (or madness ! )I have come up with a cunning plan; if it was front wheel drive then I would cut out the need for 5 miles of chain to reach the back wheel, then if it was rear wheel steering, issues of -chain meets wheel as it steers' are sorted as is the need for much gubbins to steer 2 wheels. What do you recon ??
Also ,have you any bits ?? like stub axles & hubs or do you know a way of converting ordinary hubs to go on stub axles ??
