I wear CIC (Completely-In-Canal) hearing aids all day, about 16 hours - it does impact wax in the ear canal, but otherwise no adverse effects.
Thinking about it, this functionality would best be achieved by allying with one of the CIC hearing aid makers - they have the hardware capacity and the technology to deliver something like this.
