You cannot gain power of attorney for your brother without him granting it to you. If he is in need of assistance and will not agree, you could seek gardianship or conservatorship through the probate court.
Only your brother can grant you power of attorney. If he is not willing, and you give no reason why he should, then the only other way is to be appointed conservator for him. But he would have to be incapacitated and then the new wife might challenge it.
