I can understand that when events have been out of your control, the temptation to lavish gifts on her must be very strong. It’s one thing that you can control in a very tough year. 
But I just want to say to you not to underestimate the impact of your love and support. I’ve been through some pretty rough times in my life and I am so incredibly grateful to my parents for their support and love.
Sometimes providing consistency and certainty can be a hugely important gift to a child if life has left them vulnerable or fearful. And while it sounds like a dream come true to get every item on your wish list, it also could be a little bit destabilizing. Children look for boundaries in different ways. We’re all familiar with the idea of a child acting out, needing an adult to firmly and gently set limits. No limits can be frightening.
If you buy everything on her list, you may as another poster said be setting up expectations (and possibly disappointment for the future). But I’d also be concerned that you could be burdening her with the responsibility to make wise financial choices at an age where she should be indulging in flights of fancy. My dc have circled three quarters of the smyths catalogue and written wish lists of lego sets that they don’t even make anymore. It’s just good fun. They don’t have to be sensible because that’s my job.
Whatever you decide to do, I hope the two of you have a lovely Christmas.
On the subject of “big gifts”: If I take my dc into a toy shop they are drawn to one or two things. Then they look at everything else and then they come back for another look at those one or two things.
Those, regardless of cost, are their big items.
