As long as it slows the a$$ end down it will do the trick. If it alters your arrow flight that much, it's probably more of a mental thing at that point. I often mix primaries and secondaries, not to mention species of bird, on the same arrow. I don't mix and match left & right wing. That will alter spin in flight. One of my current favorite hunting arrow looks is Canada goose primaries combined with an osage-dyed turkey primary for a cock feather. For some reason, I tend to use the two fletch with turkey tails on my shoot shafts where I prefer the three fletch on my doweled and boo shafts.
