I have read about a plan to use solar-powered ion thrusters to place a large asteroid outside the orbit of venus and drag it gravitationally outward into a zone where it would be habitable. If I remember correctly, the process was supposed to take 6000 years.
Presumably if you could do that, in 10 or 15,000 years you could keep one inside Earth's orbit and drag it incrementally down into the Sun.
