Provided you go in with low expectations of it ever happening, sure.
Why would I have anything else? Lol.
As for sales, given that Seven Seas licensed Yabuki's other series, Darling in the Franxx, and even nabbed the Ayakashi Triangle license from VIZ, it's probably safe to say that To Love Ru & To Love Ru Darkness didnt sell poorly. Tho yes, they presumably they didnt sell well enough to justify immediately licensing the light novels.
why would JNC want it?
Because I want to buy it and read it! Because other people want to buy it and read it! Lol.
In that case, Seven Seas would be much more likely to get these novels instead of JNC anyway...
Again, there's literally no harm in asking JNC to get it, so I dont see your point. I'm not claiming it's likely to happen.
