Wow, that is lucky. I have been thinking about doing this for a long time and my solution has always been to use disc brakes which is turning out to cause a bunch of other issues. However, they do make those extenders for canti and V-brakes. I can't remember what they are called, but they add another 3/4" or so more capacity, so you and your buddy should be able to make those brakes work with any wheel that is at least a 26". That is as long as you can find those extender things.
The bike looks good! Further inspiration for my project.
