Remove The Raw Blackstone From Bastions

Bastions, or Bastion Remnants are quite interesting and cool structures (apart from their horrible exterior design). But what makes it worse is the use of raw, natural blackstone. I really don't like the way it looks in the Bastion Remnant structure. It makes it feel like a cave, not a ruined fortification! If Mojang made it so that there was only blackstone bricks, and cracked blackstone bricks, I would be very grateful! Please vote for this, if you want to make Bastions better!
