Airplay to virtual Chromecast

Hey guys,

I’m an Android user with a Nuvo p3500 amp (whole home audio). I have a single Chromecast Audio hooked up. So today I build a zone in the Nuvo app and use the Chromecast as the source. It works fine

My goal is to have a single app experience. Interestingly I had a family member over today and the Nuvo supports airplay. Each zone shows as a separate airplay option

I’ve seen aircast. That appears to be Chromecast to Airplay. Id like HA to take these Airplay devices and make them appear as Chromecast on my network. Obviously I could buy a Chromecast for each. But that’s a pain. Anyone doing this?
