I brought the Rox risers, Air Hawk, and the Ram system back from the USA in a suitcase as I could never find them here either. The 2" risers worked with no problem for me regarding cable length. It was close but worked out fine after I carefully adjusted the front brake hose. Picture above shows the hose now pointing down rather than horizontal. Just had to be careful not to get any air into the system.

I am still trying to find some good hand brush guards to go on. The set I have sourced as others here have did not work on the protaper style handlebars for me. This will be next farkle for me.
