Baroness title is confirmed still in game. I just received it on my female Bounty Hunter.
However there is an important part of that discussion one needs to do.
When given the option of who to choose, choose 1: The young hothead (Raffid)
Now this is the important part. At the next convo option DO NOT choose the one about keeping it casual, choose instead 2: Works for me.
Not sure about the last convo option but I chose 2: Would if I could.
Its that second part that's important. If you choose "keep it casual" you will not get the Baroness title, but the Knight of Alderaan title (Been through 2 female bounty hunters and can confirm this). You need to choose "Works for me" to make the marriage something more than just casual/professional.
Also race I don't think matters. Got it as a Zabrak. Hope this helps all the other female bounty hunters out there!!
