You can merge them together if you'd like, making sure GRF with the blue tiles overwrites the GRF without.

Before you merge files make sure you have a backup. It's impossible to make a merge undone.

You cannot replace it with common sprite files. But you could replace it with a treasure box instead.
If you want to costumize the emp you need to master a 3d tool.
