[Research] Need help with Wasted Screen (MP_BIG_MESSAGE_FREEMODE.gfx)

[F122]

I've been trying to modify the wasted banner size and text size with no luck, I know for a fact that this is possible because this has been done before (see Old Gen HUD mod).

So far all I know is :

1. The wasted banner is inside this mp_big_message_freemode.gfx file (found in update/update.rpf/x64/patch/data/cdimages/scaleform_generic.rpf).

2. You can open this using FFDec (look it up on github)

I would appreciate any kind of help on this.
