The DM can post it's "wish list", but it won't happen. If Beatrice and Eugenie weren't given more Royal Duties by QUEII and her son, now the King hasn't overridden his late mother's decision, the list of "younger Junior Royals" aren't going to be tapped. All of these young women and men have careers. The public wouldn't be too fond of an increased list of Royals performing Royal Duties. If you read the comments, more are bringing up the King's wish for slimmed down Monarchy while others are bemoaning the "costs".
