How Quickly Could Venus Be Terraformed?

Yup, I think she left no one on Earth anyways but a few friends and one best friend. Not a lot of people to miss. But for me, I wouldn't want to "time travel" to the future with no means of going back in time!

In real life, technology would actually catch up to it literally.... Before such ship arrives in its destination in 120 years, a faster-than-light propulsion would have been invented by then and catch up to the ship.

My plan for such interstellar voyage is to have the entire propulsion system replaceable in transit -- Similar to the configuration of Galaxy-Class starship in Star Trek where the engineering/propulsion and habitat section could undock and fly independently.

Let's say during the voyage, a much more advanced and much faster propulsion was invented back on Earth, the new propulsion system would be flown and delivered to the starship in transit and replace its current propulsion system would enable it to reach its destination a lot sooner. The older but slower propulsion would either be delivered back to Earth or destroyed completely by flying it on a collision course to a nearby star.

Plus, if we had the capability of terraforming the disaster of an atomosphere of venus we could also reverse the damage we've done to our own atmosphere.

The surface gravity on Venus is only 0.903 times the Earth's surface gravity. It is the atmospheric pressure that is 92 times the Earth's atmospheric pressure.

First we'd need a significantly sized mirror for a significant incoming solar energy reduction. Then drop a ton of large ice comets into it.
then wait for a thousand or two years for thevplanet to cool enough that it could be seeded with microorganisms that use carbon dioxide and sulfur and then wait another couple thousand years... Perhaps in the meantime harvest various gasses/materials from it as well.
