It could be a tool used for that discussion. Assign everyone both versions. Then discuss the ways the simplified version falls short of the original (and, because teens rebel, the ways it's better) so that by the time you're done, the kids who struggled to read the original will get more than the easy one could give them (and have really bad errors repaired) while the easy readers will have honed the ability to break down complex concepts. The middle kids will get a bit of both. And there's bound to be examples of the way words change meaning over time.
