I had a similar idea years ago -- but the design I came up with was ridiculously (in retrospect) overcomplicated. More recently, I discovered that the devices are now available for purchase. The design is somewhat like what you envisioned -- except that a normal drain pipe is wrapped with copper tubing for the intake water. That avoids the clogging problem.
There ya go.
Effectively 7kw in free power while the shower is running.
