Barley wine

[SMOKEU]

I want to make this kit here Muntons | Home Beer Making but I have noticed that it only makes 13 litres. I can't be bothered sanitizing my fermenter and bottles just to make 13L of beer, so I was thinking off adding 2 of these kits together and 2kg of dextrose, and then topping up with water to 24L and adding 2 packets of yeast. Does that sound like a good idea?

I would go with malt extract (any color) instead of the dextrose, personally.

It would be drinkable with dextrose, I imagine, but kinda thin.
