if she wanted her daughter to be a surrogate, there are much easier ways. my brothers wife couldnt bear any more children after her first. so they took his sperm, her egg, and had my stepniece (17 at time of discussion, 18 for procedure) bear the child. i remember the conversation the family was having around xmas and all of us were really happy the daughter (my step niece) was willing to bring the child to bear. i think they also paid her like 100k or something so she was pretty happy to get a jump start to life. anecdotal i know but its not as weird to talk about or do as one would think.
