How to change screensaver for time of day, using shortcuts on macOS

I am aware of dynamic screensavers, however I want to take it a step further by using, specifically, the Sequoia sunrise screensaver at/during sunrise/daytime hours and the Sequoia at Night during night hours. Make sense? There are three variations of the Sequoia Forest screensaver but they do not automagically change depending on the time of day. Is this possible? I know it is  Community, and I know we all love a challenge.

Help me out here!
