In sports where performance is key, no. Even if they create different leagues for natural contestants and contestants on steroids, the steroid one will prevail leaving natural leagues in the shade. Then there will be a contest of who has the best doping, steroids etc.
This is how it is in bodybuilding for example, the most popular "leagues" are the untested ones, because those interested in the activity want to obviously see more striking results.
