The ATEM Mini switchers are HD only, so they will only accept a maximum resolution of 1080p60 on their HDMI inputs. Which means that if you send a 4K signal from the Elgato 4K60 S+ passthrough output directly into one of the ATEM Mini HDMI inputs, the 4K video signal will not be recognized.
So, you would either need a 4K capable video switcher (Blackmagic does sell several 4K switchers, but they are more expensive than the ATEM Mini and don't have built-in recording or streaming features). Or you would likely need some kind of video scaler to take the 4K video source and downscale it to HD. The Teranex AV can do 4K to HD video conversions, but is more of a broadcast-oriented unit, so it may be a bit more expensive than you are looking for. And it also adds 2 frames of latency when doing video scaling.
So if you wanted to go down this path, you might investigate some of the more consumer oriented HDMI video scalers. For example, there are some HDMI splitters that can take a 4K input signal and do a 4K pass-through on one output and a 4K to HD down conversion on the second output. HDFury makes a couple of products along these lines, such as the Vertex and Integral 2.
From your description, it is a little unclear what other video sources you are sending into the ATEM Mini though, and why you think using it would improve your workflow. The ATEM Mini lineup are primarily designed as multi-input video switchers, that also have some streaming and video recording features built-in (depending on the model).
