Howdy,
I’m looking for a feature of idea crowdsourcing
Something like this:
Is it possible to do something similar with Discourse?
It’s not part of Discourse core features (and never will be) and there’s no plugin I know of that does that. Your best chance would be to create your plugin to add that feature 
A bit of a “dirty” solution, but this may be doable by hijacking the “likes” system… essentially you remove the “Like” button and replace it with a “Vote” button and display the number of likes as votes instead… would take some thought, but the mechanics are pretty much the same thing unless I’m missing something obvious.

Update:
There is a proper spec for this feature here:
