Exactly. They had Commonwealth roles so they could have gone to live in a Commonwealth country such as Canada which would be relatively convenient for Doria and worked from there. If that wasn't enough, they could have added in other stuff such as military charities, the UN, supporting women, and so on. It does seem that the RF wanted them fully 'in' as it were though. Queen Elizabeth (at the time) was also Queen of Canada, Australia, New Zealand and other nations so having members of the RF living there instead of just visiting would have looked good and they wouldn't have had the constant comparison with W&K. Maybe that was too experimental for the old guard.
