You can be assured the component manufacturers would happily sell "certified" gear, and lots of us would buy it imitating our heroes etc. The parts can be identical to the parts used in training. Said certified gear can meet the olympic standards for data integrity. The cycling industry adores selling "pro" gear to amateur customers and the associated markups (UCI approved!).

This is not that different to amateur motor racing, where its expected you only bring a helmet that's certified by an external body (Snell/FIA etc). There are generally only a handful of pedals designs in use in the pro-peleton today, so not like we are talking about moving a mountain, and the UCI already regulate a lot of existing parts.

As I said, I suspect this is not the main problem with this approach, there are likely many other much better reasons why this isn't a good idea.
