As has been said many times before, the original brakes on the Twenty are unconscionably bad. Think of alternatives for the front brake. I used a drum brake front hub. Also, the rims are super heavy, so aluminum rims will be a plus.
I have been tempted to fire up the torch and add V brake bosses to my rather stock 20... have done this for a number of customers as well as my own P20 which stops as well as any bike I have ever owned.
Touching up the paint afterwards would be the biggest challenge.
