when i was a kid we would take these and just flip the forks, and the back end and make them lowriders. now that i think about it, this would be my first altering of a bike. i mist have been 5 or 6.
Very cool.
Do you know how you are mounting the seat? Maybe you could make the seat adjustable along the length of the top tube. Drill several holes and put a threaded rod on the seat.
