How can one reconcile a son's desire to honor his deceased father's mother and house her with him, while avoiding potential problems with his wife, who is sensitive towards her husband's family and influenced by her own mother, knowing that he fears his wife's reaction and the possibility of conflicts that could affect their family life?

Both the mother and the wife have rights over a man, and he must reconcile between them as much as possible.

One way to reconcile between these rights regarding housing, if the wife refuses to have the mother live with her, is to rent a spacious house and allocate an independent section for the mother, or to hire a servant for her in her own house, while ensuring to visit her and treat her kindly.
