I kind of hope that Beatrice and Eugenie have more of an official role within the Royal family. If we jump to twenty years into the future, there's a good chance that there will be three main royal couples, with Charles being a 90 year old monarch with his siblings taking a back seat due to their age. The little princes and Princess will likely still be in their education/seeing the world phase, so having Beatrice and Eugenie in an official role may help ease the pressure on the three main royal couples, and allow the many patronages supported by currently eleven or so royal members to continue and to be highlighted.
The BRF needs to give Beatrice an official role because let's be real the Willnots and the Luggages only want the glam engagements so the bread and butter stuff will be severely under served.
This could be her niche, as it's not glam and won't overshadow the 2nd generation Waleses. She would be a combination of the Kent's and the Gloucesters in the next 20 years.
