Dynmap Structures

Is there anyone fluent in both Spigot/Bukkit and Sponge?
GitHub - KovuTheHusky/dynmap-structures: A Bukkit plugin that shows your world's structures (such as Villages, Strongholds, and Pyramids) on Dynmap. would be very appreciated to be ported/rewritten to Sponge for 1.12.
I tried, but got quickly overwhelmed both by the amount of stuff changed in the plugin itself and in Minecraft’s biomes.

Well, I still can do it, but I could use some pointers.
