I think they would find it weird or use it to reinforce feelings of their own supremacy.

First one, obvious because of the reasons you stated but also because how it against the ponies natural reaction/stereotype. Seeing ponies fold and freakout at the face of danger is so often the norm that the embrace of this holiday might really confuse them.

As for the second point: imitation is the greatest form of flattery and I could see the changelings running with how being able to change is a desirable trait that THEY have and others wish to have.

I have a lot of other stuff to get to here, but till then HAPPY NIGHTMARE NIGHT!
