I took the eyes out, it's more of a ball that spins on an rod with a weight on one end. So you could probably make your own, but there just isn't much demand for re-makes of the eyes themselves.
You could always find a super baity BBE, or make it a DBBE by filling the eye holes with clay and painting. Maybe there's a set of dolls with blinking eyes that might be well-fit for replacements if you'd prefer to keep the BBE aspect.
