GVR Hack for Unity iOS build pipeline on Windows

So, unity spits out a xcode project and workspace. this work space requies cocoapods which is mac based.
is there any hack for this for the windows platform.
I am using the iOS Builder (windows) which works perfectly up until enabling VR (GVR Cardboard)

Could a prebuild cocoapods project be injected using a batch job in the build process?

Or any other alternative hacks for VR on windows to iOS.
