Installation over old doorbell space

My house currently has a doorbell that doubles as an intercom. The intercom is old and doesn't work so it's been disconnected. I was going to install the Ring 2 Video doorbell, but the space where the current doorbell is installed is larger than the Ring doorbell. Just curious if there are adapters available or if anyone has dealt with this. I was considering just using a piece of finished wood (and painting, etc so it looks nice) but I'm a little afraid it will look terrible. Any suggestions are appreciated.Thanks.
