yeah, 2 kilos would bump it up into the realms of 6% i reckon. won't change the taste too much, normal sugar pretty much ferments completely. in beer it leaves a slight cidery taste but the ginger should more or less overpower that. try dextrose if you don't want to risk it. BIG W, Kmart and some supermarkets have kilo bags of dextrose.
Actually honey is only 50% fermentable from what i understand. If you bulk prime with honey you need to add twice as much. At least thats what my bulk priming calculator tells me.......
