Harry Turtledove wrote the novel, "World of Difference," where Mars is replaced with Minerva, a habitable world slightly larger than Earth. That got me thinking about a somewhat different alternate history.
Would it be feasible to park a habitable planet, perhaps somewhat larger than Earth, in Venus's orbit? Or is Venus's orbit too close to Sol for any long-term habitability?
Also, would a somewhat larger planet in Venus's orbit (say, 2x Earth mass) be a problem for Earth's orbital stability?
