I believe one of the reasons for the Kinetic Novel route was to reduce branching/dev time. Changing story and renders for different combinations of girls would be a headache, and so would changing Jack/Jackie's gender. So I wouldn't expect that to be added.
The lesbian content will also be limited - essentially some girls may be around/interact during mutual sex scenes with Jack. But the dev sees them more as "sister-wives" than actually into each other.
Sorry to hear that invalidates your ability to play, it is a wonderful story.
