Lets assume we as humankind can, not only wormhole the spacecraft, but planets and moons. So, what would've happened to Earth if we pulled Europa to be Mars's third moon? What if we moved Titan in between Mars and Jupiter, setting it to orbit the Sun just like a planet. What would've happened to us? Climate and tides? If there are something extra bad comes with it. I'll be eager to know. I'm also interested on how many of those small moons we can make to orbit Mars, Earth and/or Titan? Such as Iapetus,Rhea,Enceladus,Tethys and Dione. I'm interested in this cause, if we moved those filled with ice moons closer to the sun, we might use our Sun to melt it down. If we at first, travel them through portal like structures next to Venus. We can heat it up, so it melts faster for calculated time and then send it back towards Mars. Iapetus & Rhea are roughly 1/2 the diameter of the moon. Tethys and Dione about 1/3rd the moon's radius. 363,104 km is from the center of Earth to the center of Moon. Which sized moon will be the safest to orbit our planet and how far (roughly) it must be located from the Moon? I know that our satellite keeps moving away tiny bit year by year. Just to make sure that it will be there till we gather all data on undiscovered elements, use full capacity of water, finishing of with a high tech too dangerous for Earth lab on the surface.
PS: assuming that we can wormhole safe water from the moons onto Earth

what would've happened to Earth if we pulled Europa to be Mars's third moon?
The moons of Jupiter & Saturn have fairly stable orbits because the gravity of the planet overpowers other influences from the distant Sun, and other small moons circling the same planet.
Moving Europa from Jupiter into Mars orbit would have a major effect on Mars' two small moons, Phobos & Deimos. Europa has around 10% the mass of Mars (Europa similar in mass to Earth's Moon). It is possible to select an orbit which would be stable in the short and medium term, but in the long term, the eventual chaotic motion of the Mars system would result in Mars' two existing moons being thrown out of orbit, or crashing into Mars or the relocated Europa.
This chaos in Mars orbit would not affect the Earth (unless the small moons being ejected placed them on a collision course with Earth).

I am much more interested in the possibility of life inside these icy moons (and the remoter possibility that we might even be able to detect it, let alone understand it). Just melting it or mining it would likely destroy any signs of life that may be present.
If we could zip around the solar system or galaxy at will, I don't see why we would need to go on a rampage, destroying potential habitats before we understand them, like a space-age Attila the Hun.

"till we gather all data on undiscovered elements" Yes, I'm aware of that, so we will research first before we exploit.
