Sorry about the wait golden, however, I have finished your Block while the forums were down. Hopefully, you'll like it. I had to modify it slightly though, to make it fit the 32x32 block I had to remove the crossbones. Other than that it is basically what you asked for. I don't know what block you want it to replace, so it currently replaces the SMW Spike Block, as I figured a Death Block would either kill or hurt you. If you want it to replace any other block, just change the block ID number eg: block-340.
