It's been hinted that this may be relevant to the DLC. The dev has acknowledged that people really like that character and would like her to join your party, and the DLC will have new party members. Incidentally, there's an incomplete ship in that character's lab that seems like it would be a great way to leave Gianna and visit foreign lands... I'm guessing you'll get to transfer her soul from the fake orb into the cloned body that's currently regenerating in another lab, and then she'll take you to the DLC area.
Vemix is kind of a weird spot where I am not sure if Vhiel will actually release her despite popularity.
Going by in-game files: she does have unused equipment that you can only access through cheating, one of which is a pair of glasses that possesses the wearer with Vemix's spirit, gloves for Vemix to use (which also unlock her unique skills), and an item to force-remove the glasses+possession status. Reason she wasn't originally in the game is partially due to how hard it'd be to program having her possess a party member, but at same time having spoken with Vhiel before: they were not fully against the idea of still bringing her back in. Very whishy-washy responses on it.
The computer lab/crashed ship, from in-game files, shows two things of interest: a new (helpful) NPC and a machine that turns your characters into androids with some form of memory rewrite already written. I think it's coming in the next DLC if not mistaken, forgot what Vhiel said is in the new DLC beyond the dwarven stronghold (northern part of the continent), one new party member, and Giana's magic academy (expansion to the capital.)
