Okay, then I'll start with Gotham Academy. Make it a manga, as in black and white. That's their target audience anyway, so make it cheaper with many pages instead of fewer pages but with gorgeous art. Yes, there are people who can afford that but if they really want kids and teens to buy them it should be more pages for pocket money.
No, better, since we're in COVID mode, turn it all digital. People are reading on their smartphones. Also, don't sell it more than 99 cents apiece, because, in the general audience's mind, digital comics don't worth as much as prints. This way you can even keep the art full color with fewer pages.
Also, they need to take a look at the Webtoon format from Korea. Those are really popular.
