Spartan and Fire Mod 1.12.2 mod adds Dragonbone, Iced Dragonbone, Also Flamed Dragonbone weapons for Most of the Spartan Weaponry variants.
The recipes are a little funky as they use the Spartan Weaponry Hilt/Hafts instead of the Ice and Fire ones, the possible future goal with this mod might be to implement an equivalent Haft for your Dragonbone weapon hilt and possess recipes more in accordance with the default Dragonbone tools.
