While We're Venus-forming Earth [1]

I often joke that people are fixated on terraforming Mars because we’re busy Venus-forming Earth—we’re just stepping it out one orbit.
Well, here's something else we haven't tried yet:
Venus does not have a magnetic field. To have one, it'd need a spinning, molten iron core. Therefore, crash 16-Psyche, a large nickel-iron asteroid dead center into it with enough velocity to puncture and cause a massive heat reaction. Start dragging large asteroids into a solar orbit that will cause them to: coalesce into a single loose but large mass. (this is the clever/tricky part) swing past Europa with enough inertia and gravitic pull to nudge Europa out of Jupiter's orbit into a decaying solar orbit. Using the coalesced asteroid gravity tractor, nudge Europa into an orbit that swings past Venus in such a way to gradually drag it out to an orbit at 1AU (earth's orbit) diametrically opposite Earth in our orbit around the sun. Gently crash Europa into Venus. This will give Venus liquid water and raise its mass to 89% of Earth's mass. Add more and more asteroids and several of Jupiter’s smaller moons onto the coalesced asteroid tractor until it reaches roughly 89% of the Moon's mass. Then park it in orbit around Venus at roughly the same orbit as our Moon around Earth. Seed the hell out of Venus with algae and such that will absorb the CO2 and sulfur from the atmosphere and excrete O2. Wait a few millennia for the surface to cool and the atmosphere to stabilize and move in.
Of course, it might be a lot easier to terraform Earth back into a habitable planet.
Technically easier, that is, not politically.
