I’ve seen his books translated into multiple languages and fans of his that read him in those languages. I think with a capable and dedicated translation team you could have a reasonably close translation, though some linguistic jokes would likely be lost. Then again, a single Discworld book has insane joke density, so losing 2-3 isn’t the end of the world.
Like Emma had been writing some awesome Morrowind mods for ages - she was involved with a massive project that brought children to the game, wrote some of the pioneering companion mods for that game - and then she got to collaborate with Terry fucking Pratchett on one of the best Oblivion mods ever made.
