Yes it will in a way. Deleting a sim leaves all the portraits in the family tree where she was shown blank. But you can fix that. It takes some time and has be done carefully but since you use MCCC, it can be done with the Relationships option. You can reestablish all the main relationships - wife, husband, mother, father, daughter, son.
If all the relatives are still in the same household, it's pretty easy as all the sims you need to connect to are in one place and the new sim will have met them automatically. But all it takes to do it for relatives outside the household is traveling to their household. The key thing is that you need to meet them and get them into the replacement's relationship panel. Click on the replacement to get to MCCC and click the relationship option. Then work from the top down along the family tree so to speak. Husband first, then children. If there are grand children, those should self correct once you reestablish the relationship with the children.
I've used it quite a bit when I last started a new save and brought sims into it from an earlier or another save. Every once in a while, I do have a problem with getting a relationship to reset but eventually it will if you keep trying though. Sometimes you have to save and exit, delete the localthumbcache file and try again.
If you have never used the option and/or feel uncomfortable about doing this, make a copy of the save and put it somewhere safe before you start. Once you've tried it and see what happens, then restore the save and go for it. Actually, you should make a copy before doing anything like this just so you can recover if you need too.
If you need any additional help, just ask. Hope this helps.
