Yes you can train her too go outdoors.
Also, if you start with pee pee pad training, you can always transition to outdoor in the spring when it gets warmer.
My Yorkie is trained both to pads for when I am not home and also to ring a bell to go outside. Yes it can be done.
I also had an older Maltese (RIP) who I trained to pee pee pads at the age of 13 after she had been outdoor trained her whole life.
I would recommend washable pee pads, and use her own urine on them to entice her to use them
