No human composer will ever produce convincing imitations because the only test that will be accepted as "convincing" is the judgment of an expert. Experts are familiar with the complete works of those famous composers, so they will immediately know the imitation is an imitation. Their knowledge makes them incapable of unbiased judgment. A blind test is impossible. Even tricking the expert into thinking a new genuine work has been discovered won't help, because they will know that is much less likely than an imitation being written. I've listened to a lot of music by those composers, but not all of it, and I'm confident a skilled imitator could fool me.
