My gf’s sister in law?

recently started dating a new girl. She’ll be traveling abroad soon and will be staying here with her brother and sister-in-law. She constantly complains about her sister-in-law and even says they should have more sex because they always fight. She mentioned that she, along with her brother, will be back in her country while her brother’s wife stays here for the whole summer. They are my neighbors. I can’t stop thinking about her connecting me with her brother’s wife so I could “bring her back to life” while they’re abroad. I think my girlfriend would be totally fine with that since she is slutty and doesn’t like her sister-in-law.
