Just noticed on the bronco sport that either they made some color matched lettering, or you can take the text off and they are swappable or removable and you can paint them. Hope it’s the same for the big pappa!
I thought someone on here said that when they saw one of the broncos in person, the white letters looked like they were caps on top of the regular black letters. I'd assume you could easily swap them out, since everything is supposed to be modular. I know on the sema video they confirmed being able to switch grills, so I dont see why you couldn't change out the letters if they are indeed just caps (hopefully they are). If not, like @Ares said, you could 3d print or letters, maybe even cnc machine them if you have the capability. At the very least, you could plastidip them, and just peel it and put a new coat on every year.
