One of the best mods I made was to fit 30mm risers to lift the bars.
30mm is about the max with the stock cables unless you are moving the bars away from you.
For me its much more comfortable and also slightly moves them back as well.
You could always rotate the bars a bit as well if you want to get them a bit closer.
