Possible to customize Mushroom weather chip card to include more data?

I’d like to include things like humidity and wind gust to the Mushroom weather chip card (the underlying sensor has that data).
Is it possible to add that?
Alternatively, I could create my own template chip but the one thing I cannot create on my own is the weather icon/image based on the text, e.g. “cloudy” will give two little clouds.
Does anyone know if either of those approaches can work and how to accomplish it? I’ve been doing a lot of google searches but no luck so far.

Thanks!
