[1.12] Advanced usage of INBTSerializable

Hi !
I'm using different types of maps that I have to Serialize to NBT, because they'll be saved in a TileEntity data.

So, I decided to create a generic interface for my tables called ITable :
 

package com.github.franckyi.netcraft.logic.tables;

import java.util.Iterator;
import java.util.Map;
import java.util.Map.Entry;

import net.minecraft.nbt.NBTBase;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.nbt.NBTTagList;
import net.minecraftforge.common.util.INBTSerializable;

public interface ITable<T extends Map<? extends INBTSerializable<? extends NBTBase>, ? extends INBTSerializable<? extends NBTBase>>>
		extends INBTSerializable<NBTTagList> {

	public T getTable();

	@Override
	default NBTTagList serializeNBT() {
		NBTTagList nbt = new NBTTagList();
		for (Entry<? extends INBTSerializable<? extends NBTBase>, ? extends INBTSerializable<? extends NBTBase>> entry : getTable()
				.entrySet()) {
			NBTTagCompound c = new NBTTagCompound();
			c.setTag("Key", entry.getKey().serializeNBT());
			c.setTag("Value", entry.getValue().serializeNBT());
			nbt.appendTag(c);
		}
		return nbt;
	}

	@Override
	default void deserializeNBT(NBTTagList nbt) {
		for (Iterator<NBTBase> i = nbt.iterator(); i.hasNext();) {
			NBTTagCompound c = (NBTTagCompound) i.next();
			INBTSerializable<NBTBase> key; // I don't know what to do from here
			INBTSerializable<NBTBase> value;
			key.deserializeNBT(c.getTag("Key"));
			value.deserializeNBT(c.getTag("Value"));
			getTable().put(key, value);
		}
	}

}

But I'm having trouble deserializing the NBT tag to my Table.

Should I let the subclass implementing ITable override deserializeNBT, or is there a direct solution in the interface itself ?
