Don't recall anyone saying they had replaced it all--usually the problem was the stuff had rotted and was just coming out the holes in chunks.
Unless all bad, I would pull out the worst stuff until you get down to what looks to be intact and then replace with the copper. If you can leave the stuff toward the top undisturbed that gives a bit of the original for filter in case the mesh isn't quite fine enough or gaps are present. Of course, if the Kapok is compacted so bad air can't get thru or it's flaking off and can get into engine, then would replace.
