I think it's unfortunately a bad idea for three main reasons (ignoring any practical issues with the terraforming):
the low gravity can't be changed, and can't be ignored.
the lack of a magnetic field means issues with radiation reaching the surface we're shielded from
the combination of these two would lead to any atmosphere we could create needing regular top ups, as it would be erroding constantly.
The magnetic field issue is a biggie, and would have to be addressed before any large-scale colonization efforts could begin, but is hypothetically solvable.
Yeah, there have to be better alternatives than Mars if we really want to have large human colonies outside of earth.
