If you blended a bunch of these rankings together, you'd end up with a consensus of consensuses. Not sure it really does you much good. Plus, none of that takes into account differences in team development, injuries that happen post-draft, etc. - see: Angelo Esposito, 2007 draft, who maybe still wasn't going to be fantastic but knee injuries certainly did him no favors.
The real value is in looking at all the rankings and spotting who does the best job at picking gems out and getting them ranked even semi-accurately. It's great if someone noted Kucherov could be a superstar in this league, but if they still only had him ranked like 43rd I'm not sure that really screams "did a great job of identifying him" because it means he's still probably ranked behind guys like Adam Larsson, Ryan Strome, Jamie Oleksiak, Tyler Biggs, and so on and so on. And I'm not sure anyone's draft rankings have done that on even a semi-consistent basis.
