Here's an idea: 1) Write a blog post about that idea. 2) Take that post to the trending page by using upvote bots.
You'll have more eyeballs looking at your post and who knows? Maybe the powers that be on Steemit Inc. would notice. Not guaranteed but it won't hurt to try.
Is it possible to upvoat comment with bidbot?
Some allow comments to be upvoted. What I'm suggesting, however, is to create a blog post about your idea and promote it.
