Shouldn't be a problem. The file you want to edit is called "glass_names.dds". I recommend just copying "\assettocorsa\content\cars\bmw_mini_f56_jcw\skins\22_powermaxed\glass_names.dds", putting that into your custom skin folder, then editing that in GIMP. It's already got an alpha channel there so you can see how they have it organized and placed. Basically black means 100% transparent, and white is 100% opaque, and you can kind of tell where a good place for your own number/name would be based on that example.
