It would be better to purchase a used jacket with big, bulky pockets and stuff the 4KG of items into the pockets....if the agents want to charge you extra.
I have seen some people wear 4 shirts on a plane. At first I thought it was to stay warm, but they were wearing two coats when they got off the plane.

I have "escalated" the "Can I use my Avios against the extra weight charges?" question to flyertalk. This is the answer:
No, not directly, though if you have a BA ticket you can use Avios to upgrade to a higher cabin to gain the increased baggage allowance, subject - of course - to availability. In some situations this may be a good idea.
But you can't currently use Avios to directly pay for luggage. However this is a study going on at the moment to greatly expand the use of Avios, to include paying for seat fees, luggage and other ancillary services. Buy on Board is an example of this happening.
