After the Graves' Cigar Controvery, are Mature Themes off the table for Narrative?

After playing 'This War of Mine', I've begun wondering if Riot will ever take the League IP in a more mature direction. It'd just be interesting for me because I've always seen Warcraft as having a cartoony/comic book feel but League had that potential to go... in a more sexual innuendo kind of direction [Janna leaked bedroom photos being the primary example].

I mean, it'd be fascinating to see Master Yi or other Ionian champs trying to survive a war-torn Ionia through an interactive point and click webcomic or VN-type interface.

Or maybe see Sejuani, an inspiring military commander, but her people living in North Korean levels of squalor, militarization, and propaganda. And the sort of brainwashing that Dai Li (from Ba Sing Se in Avatar: Airbender) types can do.

Or something entirely original carrying the essence of suffering outside the Rift.

To me, there's simply no way Riot (ESPECIALLY IN THE NARRATIVE DEPARTMENT'S CURRENT STATE) to match the sheer volume of say, the warhammer or warcraft franchises in lore. So I'm wondering if they'd opt for more memorable stories dealing with themes like casualties of war, sacrifice for loved ones, survival vs honor, and choice.

But given how allergic the current Riot appears to be towards legal issues (from comments on not reading fanfics for legal reasons to graves cigar to appeal to regional censors) I doubt Narrative has the permission to go such depths. Or the talent... then again, I can't really judge their talent if they haven't produced much.
