No.2 Mary a younger woman have children and a beautiful family.
Not necessarily a problem for some men, and is not necessarily hooker area.
Lot’s of men have done it. How much younger is the question….I do believe you can go as low as is legal depending on what you want to do.
Instead of worrying about a label like hooker I would suggest worry about the highest lever of compatibility you could get to go into that scenario. Put compatibility above the woman’s looks if you don’t want it to be too shallow like a hooker/john with kids( that goes for everybody really). Compatibility would seem to bring the woman up to at least her 30’s but there’s nothing wrong with that.
I think many 35 year old women would take a 47 year old man seriously. Maybe not a perfect match, but lets get real , few people have that. Even at 35 her clock is ticking. Make sure you tell her in advance about your plan to ship the kids off to a boarding school.
Are you capable of putting compatibility over all? I have my doubts.
