How could anyone feel comfortable with 8 people (most of them, or all of them, unknown, so belonging to your social zone) within 50cm around you, for 10-12 hours for a long haul flight?
That sounds like another way of asking "How can anyone bear to fly in economy?" Yet somehow, hundreds of thousands of people do it every day without suffering any ill-effects.
No changes will ever come to economy that will make any significant difference in the context of the numbers you're posting about. Some extra pitch? It's going to be a few more inches/cm at most. Some extra width? Even less than that.
