As a matter of practice, we don't usually share material like that, even if a project is cancelled outright. Early projects are often in a very rough form, the ideas not fully fleshed out yet or ready for any kind of public consumption. Or, sometimes material gets recycled into other projects, in either a direct way, or more thematically as foundation or inspiration for a different story. And particularly given the fervor around SoJ I would be loathe to ever share any details, since, again, even years later we receive consistent messages and demands that we release these books that we have secreted away in some final form. I don't want to encourage that behavior/thinking in any way.
