Perhaps “May the 4th” will be revealed as an actual intergalactic holiday in The Orville’s universe, which might come with a bunch of strange traditions based on the franchise.
It probably won’t happen with tons of Star Trek references (despite some shared cast and crew), but now that Disney owns the show’s Hulu home, it’s possible that more Star Wars references could creep in.
Maybe not, but that’s just one of many things the series could do to further reference Star Wars lore, and something its passionate fans may love to see.
