Run an Nx11-27 cassette, not freewheel, at the rear
This gives a gear range of 32-103 inches, where the original setup (52-42, 14-28) gave 40-100 inches
Would the triplizer bolts interfere with the crank arm? Hm...
It's a nice idea, but the extensions on Jon's would interfere with the crank spiders. Triplizers like the Merz might work, since the extensions go between the spider arms:

Salamandrine's later post made me think that the inside ledges of the spider may interfere with the chain, so you may need much longer granny bolts, if it would even work at all. Hmm...
