Prob would have kept working some jobs in Wall Market or prob try to climb the corporate ladder with Shinra because of her grades for a job she wouldn't be passionnated about as she's rather aimless & lost in BC ( she had the energy of someone who knows she had to join the Turks one day but refused the call until the events of the game) However the events of BC would prob make it that she would be in constant danger from Shinra because she's related to a Turk but is also a witness to some of the Turks-Avalanche mess ( and we know Shinra's tendencies to obliterate anything or anyone potentially leaking their secrets)

One of my bit twisted hc I like to think Rufus' father would prob have been interested in her & use the fact she was one of the top scoring students of the military school to propose her a job as one of his secretaries or executive assistants.
And knowing he has a type for blonde women around her age, well ( Annette Townshend was around 18 y old when she became Shinra sr's mistress since she was barely in her mid-thirties in TKAA) Added to that, having her around would have been a good way to keep the Turks in line as she's related to one of them.

I can also see Rufus swooping in & recruiting her before he gets an hand on her, using the fact he prob had his staff reduced while "in buisness trip" as a justification to take her away & covering all his bases with the Turks by providing some protection for her while also being a potential bargaining chip.Rufus would also need his own security & agent if he failed to save the remaining Turks as well.
So even without being a Turk, I think she ultimately would have ended up being a personnal assistant/bodyguard for one of the Shinras because the tracks were ultimately leading her that way.

If you're into more shippy stuff, you can even take the road of a fake,(maybe with some feelings turning real if you feel like it) dating AU between the events of BC and OG to show how far they are willing to go to protect each other from Shinra sr while planning to save the Turks.
