Help Center - Customizable banners with carousel capability

I came across a banner on a website today that I believe would be a great addition to Zendesk Guide's default (Copenhagen) Help Center theme. See attachment.

Here are the requested capabilities:

1. The ability to easily draft and publish notification banners in the Help Center, including options to pick an icon and background color.
2. The ability to configure and save multiple banners for later use, or have many active at once with adjustable transition times between them.
3. A publish/unpublish date picker functionality to allow for automated holiday banners.

Thank you!
