If I went ahead with her then Ulyana would be the reason Arthur went on the run in the first place. As a civilian doctor Ulyana had no real experience with the military until Arthur came into her life and when they started to pushing her into hostile actions on behalf of the government Arthur rescued her from their 'care' and headed out into the world, linking up with the group as a way to keep both himself and Ulyana safe.

Hardline would be a reluctant heroine, with the potential for mass destruction if she truly wanted but without the inclination to use her powers in that way. Having her as a pawn of the military would've been something she'd have despised, much preferring her work saving lives as a doctor to taking them as a super-powered secret agent.
