Triplanar projection NormalMap

Hi!

Anyone know how could I use the triplanar Object Space projection shader from here:
http://acegikmo.com/shaderforge/wiki/index.php?title=Triplanar_Mapping

But instead be able to use a normal map with it?

I'm trying to use this in PBR, and I already managed to modify it so it outputs RGBA instead of RGB - since I need the alpha for roughness.

Another one I'd really like to have with this is to be able to rotate the coordinates for each direction, so I can align my textures by hand. This will go on pieces of furniture and I need to be able to modify the flow of the wood grain.

Thanks in advance!
