This could be a cool feature to implement but unfortunately not high on our priority list. I would be up in helping anyone interested in figuring out how to get this implemented.

Maybe you need to add the logic to store the retrieved image into local cache dir if --cache=true here https://github.com/GoogleContainerTools/kaniko/blob/master/pkg/executor/build.go#L520
