Useing HA to Cast a Cutsom GUI to a Chromecast

I want to design a GUI that will display the weather and scroll through some headlines that will automatically cast to my living room TV each morning so that when I wake up I walk into the living room and see some useful information. I know that you can use cast to cast a lovelace dashboard but I want to experiment with casting a completely custom stream. Is this possible, and what would be the best way to go about it?
