I asked Gemini several questions about relocating Europa to a safe place closer to Earth and finally pairing it with Venus in a binary orbit. While not quite a nattering nabob of negativism, Gemini was pessimistic about the engineering to move planets because techniques to do so haven't yet been invented and published.

There should be a little how to book with dozens of techniques. It seemed it didn't want to do the math. Maybe the free version eschews calculations of that sort; something to be aware of. It did write this however...
"The idea of having Europa and Venus orbit each other is a fascinating thought experiment, but it presents significant challenges and considerations:
Potential Advantages (Theoretical):
Combined Resources:
Venus has a dense atmosphere rich in carbon dioxide, while Europa has abundant water ice. Combining these resources could potentially create a more habitable environment.
Radiation Shielding:
Venus's thick atmosphere could provide some shielding against radiation, which is a major concern for Europa.
Orbital Stability (Potentially):
If the two bodies were carefully placed in a stable binary orbit, it could theoretically provide long-term stability.
Significant Challenges:
Orbital Mechanics:
Establishing and maintaining a stable binary orbit between two bodies of such different sizes and characteristics would be incredibly complex.
The gravitational interactions between the two bodies, as well as the Sun and other planets, would need to be precisely calculated and managed.
Temperature Differences:
Venus has an extremely hot surface temperature, while Europa is very cold. Reconciling these temperature extremes would be a massive engineering challenge.
Atmospheric Differences:
Venus's dense, toxic atmosphere is vastly different from Europa's near-vacuum. Creating a habitable atmosphere would require extensive modification.
Relocation Energy:
Moving both Venus and Europa to a suitable location and establishing a stable binary orbit would require astronomical amounts of energy.
Tidal Forces:
The tidal forces exerted by each body on the other would have to be calculated, and accounted for. These forces could cause extreme geological activity.
Planetary Protection:
If Europa has life, contaminating it with earth life, or venusian materials, would be a huge concern.
Feasibility:
Currently, this concept is far beyond our technological capabilities.
It would require breakthroughs in gravitational engineering, propulsion, and terraforming.
The energy requirements alone would be staggering.
In conclusion:
Therefore, while it is a fun concept to consider, it is not within the realm of possible engineering for the foreseeable future.
While the idea of Europa and Venus orbiting each other is intriguing, it presents immense challenges.
The orbital mechanics, temperature differences, and atmospheric disparities would be extremely difficult to overcome."
