Presenting with an in-house overhead projector with a zoom meeting.

I am placing the pinned presenter view and a video on an Epson overhead projector screen, and keeping the laptop for admin functions such as invite and chat separate. We are using a Lavalier microphone setup that connects to an interface. The video and presenter are heard in the room on speakers with simultaneously broadcast on Zoom. What do you think of this configuration. Has anyone done this successfully?
