Here is an idea you might find useful.
Instead of having the chain zig zag over idler pulleys, to control it, have it pass through a long chain tensioner.
Take a length of PVC tube, about 8 to 12 inches shorter than the length that the chain needs to be. Soften and thin down the back end of it, so that it dose not interfere with the back wheel when in low gear. Put 4 idler pulleys / sprockets on it, 2 front and 2 at the back. Fit the chain to the bike, passing it both ways through the tube. The tube floats on the chain protecting it and you, and is not in any other way connected to the frame. A long strait chain that dose not flop about.
