I would talk to Rob over at Lightfoot to get his opinion. I'm not sure the conversion would do a lot of good. I owned a dual 26" Lightfoot (diff. model) for a while and found that the long wheel base and big front wheel made the rig a real handful on slow, steep climbs, more, ultimately, than I wanted to deal with for the long haul, so I sold the bike, although it was very well made and worked well with the exception of a poorly designed/placed idler. Bogiesan owns an Easy Racer's bike that has a 20" front wheel, and it's my experience that while that design doesn't handle quite as well as the short wheelbase bikes I favor, the smaller front wheel was a definite improvement. The Tour Easy was one of the best touring rigs I've owned. Unfortunately, by butt could not adapt to the lower bottom bracket. I'm a confirmed high bottom bracket guy at this point. As Bogiesan says, do lots of hills and the bike will get easier to control. Practice, practice, practice.
Best of luck with the new bike.
