I would love to see more content with the elves. They are are well written, Heloise is probably my favorite side character, and have a lot of potential for story or scenes. I could just imagine the shock on Valzira's face if she found out about Malice and if you recruited Maelys "willingly". Even just more lair event's with the other characters would be cool.
Some other thoughts/random ideas:
A way to bring Naho and Valzira around. Ijust tend to try to make as many happy as possible on playthoughs. If not completely, maybe some more "nice" options so they don't always get the short end of the stick.
A scene with Mina if you buy the bath since she talks about needing one. I know there is a scene if she's consort, but she complains about needing one if not.
More consort scenes, even the non-h ones. Sometimes, just spending time doing the various activities with your consorts is just as fun as rampaging.
Different lair/room art depending on the consort. All the consorts seem to have wildly different decorating styles based on their descriptions.
