Martian atmosphere starting from OTL 2010 is 6 millibars on average. Even with aggressive terraforming, the atmosphere ca. Fenspace's 2015 would be... 20, maybe 30 millibars. And that would still be 90% CO2 or more. Compressing that with trapar or a force field would yield a very thin layer, that might not even cover the entire planet, and it'd still be mostly CO2.
For terraforming purposes, having a breathable atmosphere is more important than having a thick atmosphere. And once the one is accomplished, the other will follow in short order. Hell, the main gas can even be trapar; just be ready to manufacture five quintillion tons of the stuff...
