I think the primary challenge JNC would have moving into the Korean market is they likely have limited to no contacts with any of the existing publishers over there. Quality KR to EN translators could also be an issue, but probably a smaller obstacle. Unless it's something they've already been doing behind the scenes already, I can't see that anything could happen in the short term, as Bookworm puts it, you have to ensure the groundwork is laid out before taking a major step like that.
That said, if you're really looking to try and get a print edition of DoD, you might want to see if you can try to steer Yen Press in that direction. Their Ize press label is already printing some KLNs like Omniscient Reader's Viewpoint, so they clearly have relationships with Korean publishers right now. I believe Publang got the manhwa print license (though I've yet to see anything beyond the announcement so far which happened at ANYC 2025...)
