Modding Request - Black Widow trait

Hi, everyone. I am doing a Black widow challenge now and I am not satisfied that my sim is sad after their spouse dies. I think that it should be more realistic that they would be happy/excited about that and new trait will be very helpful. Also, I am aware that Nisa made this trait as a part of Nisa's Wicked Perversions but I do not like that pack at all(but honestly - the idea that sim with Black Widow trait has ability to use venom to kill other is great ). If there was a possibility to download that trait separately, I would do that but unfortunately that is impossible.


My thought on it:
- it could be either CAS trait or reward trait
- sim at least should not be upset after a spouse dies, but it would be better to give them some happy/excited buff
- sim should receive some happy buff that now they got all the money
- sim could receive some bored buffs from being married to the same person for a long time
- the could receive some whims from trait, smth like 'find new romantic interest'/'marry for money'(whatever that means)/etc(I could provide the list if someone will take the request)
- would be so great to have some interaction, available only for Black Widow that allows to kill sim when you are married(I do like the idea with venom but it could be also the additional interaction for voodoo doll from the game)

Also, if anyone already has some solution to my request, LMK

Thanks!
