New mods for some boxes

I have been running strongboxes lately and aside from the pull of mobs modified by mods from this league's mechanic, some boxes like jeweler's and armor smiths offer basically close to nothing of value.

I thought maybe the following mods could be added / created for them?

Contains [1 to 4] additional with at least one [Mod list] mod

Mod List could be as follows

- Fractured mod
- Haunted mod
- Delve mod

Probably other mods missing from the top of my head, but it would make these more "boring" boxes interesting & potentially valuable.
