I'm not convinced that making an untested olympics is going to get PEDs out of the tested olympics.
Tested Olympics
After The Enhanced Games were announced, the news reported that the World Anti-Doping Agency determined that approximately 40% of the Athletes had used PED at some point.
This research statistics reinforce it.
Highlights: Performance Enhancing Drugs In Sport Statistics
Performance-enhancing drugs (PEDs) have a significant presence in sports, with alarming statistics to support it. From 2003 to 2008, 1-3% of tested athletes

Lance Armstrong
He as well as Alex Rodrigues never tested positive.
Armstrong was stripped, as we know of his wins. Tyler Hamilton, one of Armstrong team, was busted for using. Hamilton cut a deal to minimize his legal issues. That is how Armstrong was busted.
Ironically, that should have moved the rest of the Biker up in placing, second place becoming first, etc..
However, that did not happen because the other Bikers were believed to have used PED.
Alex Rodriguez
Alex Rodriguez' PED Coach/Supplier cut a deal with the feds to minimize his legal issues. To reiterate, Rodriguez never tested positive.
Tyler Hamilton
Years ago in an news interview, Hamilton was ask if was unfair if everyone is using them.
Hamilton's reply was quite interesting.
As per Hamilton, the unfairness was that the top athletes (making the most money) could hire the best, let's call them, PED Coaches
The Lower Rated Bikers could not do that. As per Hamilton, that was where it was unfair; the "Have Not" (not enough money) from the "Haves" (with enough money).
Enhance Game
This may give the the PED Athletes place to compete.
However, I doubt that it will every completely eliminate some individuals uses in Tested Sports.
