The problem is that it would take centuries of continual work to do, and way too much money.
An interesting and curious thought though nonetheless. I hope one day mankind is self sustainably living on other planets. It's the only way to guarantee the survival of the only known sentience in the universe.

Many years ago, I read an article about a plan to terraform Venus using some sort of bacteria or algae or something. Apparently this organism likes to eat the stuff that's currently in Venus' atmosphere and then it belts out the waste as something that doesn't trap heat as much. I don't remember the details, but either it spit out oxygen, or you do another phase with a different organism that takes in CO and spits out O2. The author was arguing that you could terraform Venus pretty inexpensively by dumping some of this stuff into the upper atmosphere and then waiting a hundred years. I was intrigued.
