I'd have to think it through, but if you have node red set up already check out
node-red-contrib-alexa-remote2
I set up voice announcements through Node red and completely bypassed echo speaks, which I ran on smartthings via hub connect until it ceased to function last week. Got tired of fighting with it. The node will listen for activity from alexa and connect to hubitat. From there, it's your imagination. I used the same nodes for my classic radio automation listed here.
