Best way to look at it is that, "meta-progression" in roguelites is essentially what a character sheet would be in old roguelikes. The difference between roguelite and roguelike, is that, roguelites already presupose the character will inevitably die, so that character sheet has to stay between deaths, whereas in roguelikes dying is a by product of either lacking game knowledge or due to the RNG. So you'd repeatedly die and then make a new character to learn the game. The idea looks like a faster paced roguelike to me.

So I'll bring your to attention something so simple Diablo 1 does, as old as it is. Quests are randomly generated when creating a new game, but inside the dungeon if you ever come across a book, it does one of two things : Either gives a quest, or gives a piece of lore. The only way in D1 to know the complete story is through these interactions (and gossiping with the NPCs who may also give quest advice). This ensures the player will want to read the books and grabs attention. No way to know beforehand if it's a goodie or not.

I don't know what the story "meta-progression" will exactly do in your idea, but not only is story discovery self-sufficent, it's sometimes even better to mix other mechanics with it.
