I wouldn't do it. If your brew has been fermenting away then there will be a layer of CO2 which stops the infections from getting in. Then the malt would clump and really couldn't be stirred in.
If you are thinking of doing a boil with the extra malt, then chilling to 18C then it might be possible but I wouldn't be the person to guide you through anything that radical.
You got a kit and a kilo and a bit in your recipe...this'll give it about 4.something in ABV. A little light for Coopers Sparkling but it should turn out to be a nice beer. A good opportunity to experiment with dry hopping.
A couple of days before bottling would be a good time to add some hops.
Just use the "teabag" method.
if your temps and sanitation are right you'll get a lovely drinkeable beer.
Cheers
