If you mean two hand-tracked controllers like the Rift or the upcoming Quest, that's not going to happen with the Go, it just doesn't have that capability. The headset would need to have some form of inside-out tracking which it doesn't have.
It has the remote for trackpad/menu type controlling which doesn't require tracking, so an additional controller of that type wouldn't really be a benefit, but you can use a compatible gamepad.
