daffey, one cannot take over to be Power of Attorney, only the person making the POA can assign someone to represent them.... unless that person has memory issue thus is not able to understand the legal document.
I assume this is for your Mother, who has mobility issues as per your profile, correct? Have you seen the Power of Attorney? Usually two people are named, just in case the first person is unable to continue as POA.
Your Mom can choose whomever she wants. If you and your sister don't want to be POA, then Mom can choose another relative, or a friend, or even the Elder Law Attorney to be her POA [there would be a high hourly cost for that].
