I'd put the Moon and Mercury orbiting each other where Mercury is, Jupiter where Venus is, Mars orbiting the Earth, Saturn where Mars is and being orbited by Venus, Uranus and Neptune orbiting each other where Jupiter is, and Pluto and Charon and Ceres and Eris and Haumea and Makemake all orbiting each in a ring pattern where Saturn is. Then I'll put the asteroid belt where Neptune is.
In other words, like this:
Sun --- Mercury/the Moon --- Jupiter --- Earth/Mars --- Saturn/Venus --- Uranus/Neptune ---Pluto/Charon/Ceres/Eris/Hamea/Makemake --- Asteroid Belt.
The Kuiper Belt, Oort Cloud, and everything else all stay where they are. Including the moons I didn't put on the list.
