CollectionViewHeader instead first item

Question

Can I somehow put collectionViewHeader on place of first item in collectionView, and shift all items to right for one item .

So + is header and right is actually first item in collection(index 0). Is it possible? Can I somehow do this with custom CollectionViewLayout.

Now I'm doing it with 2 different CollectionViewCell, but since I want to use DiffebleDataSource and FetchResultController, and dynamical update cell, I can't use 2 different cells(or can?).
