It would not be possible to do such a thing because of the nature of the ring, and so it was revised that he dropped the ring somewhere without noticing.
While you can say that he would be so obsessed with keeping the ring on him at all times, I think that he would have let his guard down after facing no threats to his precious for a long time.
The revision was most necessary in order to keep consistent with the rest of the lore surrounding Gollum and the Ring. I'm pretty sure we'd rip the chapter apart otherwise for how non-canonical it would feel.

While I agree with you about the chapter's revision, and that it was necessary, Gollum didn't drop the Ring. Gandalf clearly said to Frodo that the Ring voluntarily left Gollum, the reason being that the latter wasn't going to voluntarily leave the Misty Mountains. Therefore, it was better for the Ring to leave Gollum, to be picked up by someone more suitable, such that it might eventually get back to Sauron. Of course, it was picked up by Bilbo...
