You should be able to do this the same way you might add a CNAME file to your docs: https://github.com/jimporter/mike#cname-and-other-special-files

Or, if you prefer to do this within existing files, you can supply your own templates via redirect_template in your config or --template on the command line.

https://github.com/jimporter/mike/blob/master/mike/templates/redirect.html ^ this?

If I have / -docs/ -template/my-redirect.html

So in the plugin config redirect_template: template/my-redirect.html

^ would this work?

If you're on the latest dev builds, yes. On the 1.x releases, you'll need to use --template on the command line.
