You can, its a bit cost prohibitive though.
Vive / index controllers need either a vive/index headset to sync to or you can use vive tracker / steamcontroller usb dongle where you need 1 per controller. You then also need at least 1 lighthouse to actually track the controllers.
Steam vr should then be able to detect the oculus headset and then detect the vive / index controllers.
The piecemeal sales are more because the index controllers can be used with vive / vive pro systems that already have lighthouses and such.
