The problem with Mars isn't that it's dry, or even that it's cold. The problem is it has very little air and that air is mostly CO2, and is, incidentally, being slowly sheared off by the solar wind (for lack of a magnetic field). Just heating the planet doesn't solve any of that.

There's actually a decent amount of water (as ice) at/near the surface. But even if you made the planet warmer, above what we consider freezing, that ice will turn right into vapor because there's too little air pressure for liquid water to exist. The atmosphere is a challenge.

For practical purposes, the magnetic field (or rather lack thereof) is also a big problem. Even if it doesn't have too big an effect on any atmosphere we manage to build up, being constantly bombarded by cosmic radiation isn't great for living beings who want to keep living.

I think we'd be better off terraforming Earth, if that's still possible.
