Yes, it might be possible, but also expensive. But there just isn't a lot of space available to support both a good tactile feedback, and to be able to interrupt the line voltage. There are requirements for high-low voltage separation that are difficult to meet, while staying within the allowed size for a switch.

Since I'm doing it for myself, I will selfishly just do a low-voltage system :) But I'm seriously considering funding a startup to do engineering for an integrated version.

The closest thing that I found to a _good_ smart dimmer was https://www.alibaba.com/product-detail/Zwave-Zks31-Knob-Dimm... (ZKS-31). It has a physical knob as a control, and it only misses the visual indication of the current state and simulated detents.

I'm really at a loss why nobody else is trying to do something like this, while doing crap like touch-sensitive switches with LED displays.
