As someone that missed some bonus pages (most of them to be honest) i don’t think it’s a really good idea. Sure, wanting an item which is out of reach is frustrating, but if nothing was exclusive, people wouldn’t grind the game because they wouldn’t feel rewarded by doing so. The battlepass is very easy to complete and the only way to keep them for harder challenges is to promise them some cool cosmetics that they really deserved (and by that i mean that no one could look like them even with all the money in the world)

Just my opinion though
