Very unlikely chance for a number of reasons:
Life circumstances, like getting into a serious relationship/married and starting a family, often leads to retirement. While there are session providers who have romantic partners who are supportive of their endeavors, there are others who are not, and in some cases the provider herself simply doesn't want to session anymore once they are in that committed relationship. And becoming a parent is an even bigger factor. I know that Baby Blake got married and had children, so that will understandably be the priority in her life.
Fatigue. Being a session wrestler is hard work. Even though rates for them can seem high, there is a lot of effort that goes into being a good session wrestler, and I would be willing to bet that very few wrestlers make "good" money from session work, especially when you factor in travel costs, membership fees for gyms and coaches, PEDs/steroids. After while, it's hard not to imagine them feeling a sense of burnout. And that's not to mention being able to maintain a persona during sessions as being interested and attracted to a client even if said client is old, or fat, etc.
And finally, if, let's just say hypothetically, you still wanted to ask a retired session wrestler to come out of retirement, you have to be able to contact them. Wrestlers use stage names for a reason, and once they retire they will more than likely deactivate their contact information like email, social media, etc. So unless you know their real name (which would be kind of creepy to search for) and find an email address or something, you'll have no way of contacting them. Plus, they're not going to like you going out of your way to find their private information.
So my suggestion is to chalk it up as a loss that you were never able to meet those providers, and meet with someone who is active.
