The pitch/studio model does not work for short content, and it never will. It's too slow-moving and corporate. The videos that succeed in this format are zeitgeist, flash-in-the-pan trends that are faster to produce and more dynamic than even the laziest reality show. The production value doesn't really matter--if anything it's a downside past a point.
If hackathons in software work and produce good product ideas, why can't the same be possible in creative fields? Cutaways in Family Guy are already short jokes which are shared without broader context on social media and they are popular. Netflix can always A/B test newly introduced content to determine engagement. Already built up cultural context (e.g. idea of multiverse, matrix and so on)need not be re-introduced from scratch, so no need to spend screen time on them.
Odd1sOut (Youtube Creator) has a animation series on Netflix. So in some sense, Netflix is already doing it. They just have to create a marketplace for this.
