Using my ring stickup camera for watching backyard wildlife.... Really would like a camera with a telephoto lens

I've been using my stickup camera to watch a birdhouse and feeders in my yard. I'm using a tripod and solar panel. With the wide angle lens I have to get closer than I would like to. Is there any chance there is a product coming out with a telephoto lens. Or have any of your engineers or technicians done a hack to mount a C mount lens to your camera?
