To grab another idea from Niven (specifically the Puppeteers), gravity manipulation to get a small traveling solar system would probably work, though it would take an enormous amount of time. I’m not an astrophysicist, but you could get solar wind to keep protecting you from small stray objects and presumably could watch the path ahead to protect yourself from other collisions.
