I found some beer kits at a supermarket at a price that is an absolute steal, so I bought 3X 1.5kg Brewtec brown draught kits and 1X 1.5kg Brewtec lager kit. I was thinking about adding the 3 brown draught kits together to make a (strong) 23L brew, and then adding 2 packets of high alcohol yeast from a brewing shop. The cans are all pre hopped. Does that sound like a good idea? They are these kits here http://brewlion.lionshop.co.nz/default.asp?dept_ID=38
