Sadly I feel almost certain the Powers That Be will never go for this, but I think it's a good idea as long as the distribution could be done fairly. It's quite depressing to see a post get 100 votes but only earn pennies. Imagine if every single person on the platform had an upvote worth at least $1? Heck, even 50 cents or 25 cents... we wouldn't see any more $1000 posts, but we would see a lot more Average Joes making respectable amounts. And that's what this platform should focus on: empowering the Average Joe. The 1% rule real life... in the digital world of Steemit I want to turn that around and see the 99% on top.

That said, I do think your distribution model is a bit simplistic. Going by total post count will bias things toward those who have been here the longest. I would rather see it measured by highest activity levels over some set timeframe (say average number of posts per day over the last month or something like that). You can have really active, engaged users who have lower post totals simply because they haven't been around as long, and those people should not be disadvantaged.
