[WWE 2k16] Question : Arena Creator paintool injector

Hey, how are you bro's? ;) I hope fine.

I am a beginner in terms of programming, I started to look into it this year. I currently managed to inject renders for caws, championships or anything that can be moder on Xbox360 console update (thanks to KG Tools).
I would like to know if it is possible, with an editor, to inject / modify / replace for example by an high quality aprons the basic aprons of the "arena creator mode" on Xbox360, instead of use the .DDS logos 128 or 256 pixels really smaller?

I saw and upload to CC an arena of NGPW with glitched textures and modified aprons completely filled. I don't know how it work and the process.
Any advices and help welcome :)

Thanks so much guyz !

Cheers.

Ben.
