Super Smash Bros. Ultimate Ripping Project

So I noticed neither Palutena's model uploaded here nor the model in the files had her halo, so I dug into her effects files and found what I was looking for.
I have two questions on fixing this in Blender;
Is there a way to mirror tiled textures so I can fix this halo? Besides editing the UV to be a semicircle or editing the texture itself?

Secondly, what is the best node setup to colorize the central halo? I couldn't find a colorized version of it, only what I presume to be base and emission maps.
