It seems to me that, if they want to grow the atmosphere, they need to grow the mass of the planet. Mars isn’t that much bigger than our moon and its lack of gravitational pull would make it hard to hold onto an atmosphere.

Venus is 81% of the mass of Earth, yet has a surface atmospheric pressure of 92 times earth surface pressure.
