To be fair, so do the Angels and orange is nowhere near their look, not even in their alternates or anything. Probably because it's one of those things where you *could* make the connection, but it's by no means so obvious that it'd even necessarily cross your mind. And I mean clearly it didn't really influence the thinking of the original Mighty Ducks brain trust at all.
Leaning into the orange is definitely a choice they can make, but I would make an argument that black as a secondary color is a little too on the nose. For starters, orange/black is something the Flyers already do very well and 'own' in terms of people's perception. I think orange may actually work well with the purple of the original Mighty Ducks color scheme.
