Drones is spot on.
That is a very nice looking hat and at least from the picture the color is very close. The die-hards here at the Raven definitely will spot the differences in the blocking, brim shape, and the trim, but the average fan likely would be none the wiser.
I've seen for less screen-accurate hats people have tried to pass off as an Indy hat at conventions, so you'd be fine using this as an Indy hat. Plus since it's a high-quality hat, you can wear it out of costume, too!
