I tested BrianJ's solution for a Moon -> Earth -> Mars flight and on the HTO, I found our world with her little sister next to our closest star. Kinda like a transfer !
Also, completely unrelated, after some work on World Machine:
Normal maps came from the Erosion Flow Map, and the color is the "Coastal Overlay" macro. I made the actual terrain in Blender based on the height map, but I get weird results as I triangulate it for export.
