Not a straight-up Nuzlocke challenge, no, but in general, people *already* came up with various rules, like:

No using Harpy wings (and/or related abilities),

Only using the Pocket Castle when next to towns in general or Iliasvile specifically,

Reloading from the last town/last time in the Pocket Castle (or even restarting the game) when dying.

Rules related to catching Monster Girls, however, are kinda rare. You could go with "Don't raise affection (above X)", which would make recruiting harder (I had monsters join up at 40 or 50 Affection, I think - higher affection raises the chances, but there always seems to be a small chance), and you can obviously go with "Never use a girl after she's been defeated once" - but given the various one-hit kill abilities enemies have... good luck with that.
