In truth, these cats need to be spayed and neutered ASAP or you are going to have lots and lots of cats to deal with. If you keep waiting one or both of them is bound to wind up pregnant. If you continue to wait, you will then need to care or tame many more cats. I would concentrate on TNR and then setting up an inside space to socialize them.
The cats may need to spend time inside a home for full socialization. If not they will be quite difficult to adopt out.
