I didn't talk to visas when she first joined the party so i could make sure handmaiden didn't get mad. When i finished with handmaiden and had turned her into a jedi, i then went and talked to visas and in one of my first conversations with her i managed to get force sight which as Stargate: 2000 said is pretty much the only thing worth talking to her about. As far as i know this is the only way to get everything offered by both handmaiden and visas. I haven't tried just gaining loads of influence with handmaiden first so i don't know if it would work.
