Meh, I guess we'll never know. If she really lived for attention, I don't think she would have gone short of it - her jetsetting, celebrity friends, boyfriends, clothes etc would have kept her in the news around the world, unrestricted by the niceties of actually working and following the royal rules. I think she likely would have fought hard for (not with) William and Harry behind the scenes, for sure, but I really can't imagine her trying to compete with Camilla and Kate, because her celebrity would likely have always outshone theirs on the broader stage. And every time there was a big moment - the weddings, the babies - she would have been right there.
I can see the lack of royal spotlight - especially when the marriage was falling apart and after - being a problem for someone who had been groomed for nothing else since she was a teen. However, at the time of her death she might have been on the point of creating a new identity for herself as a global celebrity, and I do think it's possible she would have continued some of the charity work. Not the little meet and greets that the Royals fill their calendars with, but the big stuff ala Bono and Angelina Jolie. I could also see her building her own brand, perhaps putting her name to a fashion label, jewels or the like. She certainly had the connections to make a serious go of it.
