It might be worthwhile to spend some time considering what you hope to gain from talking to the elders.
If this is about trying to wake them up, I would suggest a one-on-one conversation, because when they have the support of other elders (or even just their watchful eye upon them) they'll never concede anything to you. They won't allow themselves. You'll be far more likely (though still a slim chance) to achieve results by splitting them up and keeping things casual and non-adversarial. I would also pick different topics that have a greater emotional appeal. Instead of science (which will easily be dismissed by the indoctrinated mind) go with things that 1. they know first-hand and 2. have undeniable implications. I think the best example of this is the ever changing blood policy. Asking if the organization should be considered blood-guilty for banning fractions at one time but now allowing them as a conscience matter is tough to argue with. It is impossible for any reasonable person to rule out the possibility that at least one person who's conscience would have allowed them to accept life-saving fractions died before this change simply because they were threatened with disfellowshipping for something that is no longer considered a DFing offense.
If you're just after some validation, consequences be damned, then go for it. The JW cult spends so much time tearing down our self-confidence so I can see the appeal of bringing your doubts to the elders to watch them fail miserably at addressing them. It could definitely help silence that quiet but persistent voice inside that keeps asking "what if I'm wrong about this?" I would just suggest that you make sure that quieting this voice is worth the risk of getting yourself DFed for apostasy. It seems that's a pretty likely outcome if you don't compromise yourself and recant.
Best of luck to you!
