I think this is a great idea, but I doubt you will find many prominent Youtubers willing to do it. It isn't because they are selfish or don't care, but because the time invested to revenue generated for a project like this is poor, and they need to do things like pay for recording equipment and eat, all the while maintaining the popularity of their channel. To do that they need to produce lots of interesting content fast. If you can find some way to make this sexy and sell and keep eyeballs fixed for the duration of the video you might find some willing, but odds are good if you try to make a deal imposing too much creative control folks will just walk away.
