If outside training is what you want then stick to it. Since she is young and still learning you might confuse her if you sudden stop taking her outside and ask her to potty inside.
My 4.5lb yorkie is trained to go outside only. I live in Jersey so we get all kinds of weather here. Morgan goes out in it all, she's like the mail man. When she was a puppy I didn't give her any other choice. We both went outside with her on a leash and we stood there until she want. Once stood outside in the pouring rain for 30 minutes until she went. When the snow started we did the same thing. She quickly learned that she had to go quickly in that weather. When there is a lot of snow on the ground I will shovel a part of the backyard so she doesn't have to trek through the deep snow (though sometimes she chooses to do so anyway.
