I wouldn't bother, the controllers are total gash. Maybe buy some used Vive stuff and use those instead with it.
Haptics aside, what's wrong with the controllers?
Holding both an oculus touch in my hand right now and a G2 control in the other. The oculus is a little smaller and feels slightly less weighty, nothing else feels different, the triggers, button placement is the same on my fingers and feels zero different in either hand. In other words practically the same in form factor, and from usage in games i have played them with no different in functionality.
Sure they have issues with camera occlusion in certain games, but all inside out carries that flaw in small ways.
I certainly wouldn't recommend the vive wands over the G2 devices.
