How realistic is it to insist on lifestyle during on-cycle recruiting/HH meetings?

Incoming analyst at a top EB, current senior at a top target. With a lot of my peers beginning to prep for on-cycle PE/HF recruiting during the final semester, I am also starting to think about what I am trying to pursue post-IBD. Everyone talks about being really prepared/knowing exactly what you want before going into your HH meetings, but my question is: how realistic is it to demand for "lifestyle" with a PE/HF headhunter? I am talking about firms where the weekends are always freed up, never exceeding over 60hrs/week, etc. Obviously, these firms are rare but they do exist. Would I jeopardize my HH relationships if I specifically make these demands though (as in they see me as a less desirable candidate/hard to work with)?
