The tree's the best bit for me. Maybe you should buy one of those brown or white trees something like this:-

I got mine from a gift shop without lights and the bark is realistic.
Then your daughter can decorate it for the seasons e.g. Valentines day - hearts, champagne glasses, Easter - hanging decorations, summer - fairies, marabou fur trim.
Home Bargains and Hobbycraft are good sources.
It will take the sting out of losing the Christmas tree - she can transfer some of the ornaments off the tree on to it that aren't particularly Christmassy.
I keep mine in the conservatory and it's a real talking point.
Some people do a "food" tree - buying ornaments to fit. Children can also craft things for the tree.
