Some of these solutions definitely need some fine tuning...but the only one I'd definitely remove is:
The rule of upvoting before 30 minutes should be nulled.
I'm actually very ok with the concept of curators giving up gains because they vote within moments.
There are plenty of posts that randomly get upvoted without actually viewing the content in full.
At best, if you wanted to modify that, I'd consider using the same formula "Medium.com" uses to predict read time...and if it has a video in it, API call to YouTube to get the runtime for that video as well...but I wouldn't totally remove the rule.
The rule was made because of the upvoting bots, but if we remove these bots and we remove the upvoting button from the Title link page, than it shouldn't be a problem. But yes your solution sounds good.
