In my mind, that content is directly related to show production, like the character creation and pre-show videos. So to me, the Scoots stuff with the live content goes on the $1 tier.
Being that the $2 tier is Behind-the-Scenes Plus, I think more content updates on a lot of extra stuff would be interesting.
As a for-instance, the first time we've seen anything about the overlay was on the video from last night. And that was purely conceptual. If $2 could get us a look at how that's coming along more often (every once in a while, not necessarily a weekly thing), that would be great. Same goes for animation. Or cosplay design.
These are all updates we aren't getting on any predictable basis, and if JP thinks it's an okay way to bring in more money, then I think it would be a cool option to have that content on the aptly-named Plus tier. Keep the regular Behind-the-Scenes stuff at purely show level, like live show production and pre/post shows.
And it doesn't even have to be anything special - like, a screenshot of an advanced concept of the overlay or a really short 1-second shot of the line work for the animation. Etc.
And more wallpapers would still be cool.
