Then just acceplerate the sun. If we can figure out starlifting, we have to do something with the excess gas and heat. Use that to make a solar thruster. Everything in the solar system will follow the sun, so now we have 1.8 generational ships called The Earth, and Venus.
This would also give us some protection against relativistic weapons, since we could make minor course corrections and still travel in the overall same direction.
