Move or reorder content outside of parent using CSS/Flexbox

Question

Is it possible to reorder content from within a parent container to outside of parent?

I want to move content box 3, 4 & 5 from within content box 2 into content box 0 (which is after 1 & 2)

Note: I'm only targeting mordern browsers (IE10+)

I have a working example or reordering content within the same parent content box.

No. Flex items can only be rearranged with their siblings.
