You'd need a few dozen volunteers to get anywhere near statistically meaningful numbers and I very much doubt a chamber big enough even exists.
You don't have to run them all at the same time...

That's debatable, ideally you do. But once you multiply the dive times required, plus the chamber time, by the number of groups, you'll realise there's just not enough hours in the day to do this two-three divers at a time. Ethics, shmethics: getting that many people bent/unbent is simply a logistical nightmare.
You don't have to do it all in one day, and hopefully the number of people who get bent is relatively small. When DAN does research at Duke University, chambers, they spread it over several weeks. As long as the various environmental conditions (temperature, dive profile, workload, etc) that affect DCS are well controlled, it doesn't matter how long it takes to do the study.
