There's a reason reparenting is controversial. Honestly I don't think you get a do over as an adult to experience parenting. Once you're an adult, that's it. You will never get it. The idea that somehow the therapist would act as a parent strikes me as extremely creepy and unhealthy. It furthers dependence on the part of the client and once the therapeutic relationship ends, what happens to the client? They're once again completely abandoned. I didn't have great parents, they tried their best I guess but it wasn't enough. I'm not angry at them and yes I often wish my T was my mom but this is a fantasy. I know it won't happen. I'm sorry if I'm being harsh. That's just my opinion of course.
