Flint & Copper (Or alternatives to lit green fire)

Introduce a new tool like the flint and steel that allows players to place green fire. Something like a flint & copper item? I know this really doesn't make sense since it's the colission between the flint and steel what makes the spark and causes fire, but honestly, no one cares.

Alternatively, you could do like with soul fire, maybe allow player to put fire over a copper block to make green fire? This would be weird since why would fire burn forever in copper blocks? I suggest that if a netherrack block has copper under, it creates green fire instead of normal one.

Another alternative is to introduce a new block made from nether bricks and copper ingots that allows the player to lit a green fire forever.

Just allow us to lit green fire, mojang gods.
