Hmm, struggling to reconcile this statement with the fact that the bike has a basket on it.
The steerer/headtube drilling thing has possibilites, but that's not a thing a responsible builder could endorse on a forum like this.
I like Peterpan's idea of making a bar that would stick through the crown and loop around the dt. It wouldn't have to be very big. You could cover it with some shrink tubing to protect the dt paint and carry it in the basket!
