Well, I was born in the state of Florida, so maybe I'm extra sensitive to this.... but the choice of "Miccosukee" as a New World province name for Florida seems really wrong, on historical grounds.

At the time of first Spanish contact, the main tribe up in the Panhandle would have been the Apalachee, with the Calusa and Tequesta along the southwest and southern coast... both fierce tribes that the Spanish never formally conquered. Juan Ponce de Leon was killed by a Calusa arrow. Those guys didn't mess around... they were the closest thing to an Aztec equivalent in Florida.

The Miccosukee Indians are offshoots of the Creek, who lived in Alabama and Georgia (just north of Florida). As far as I know, their main contact with the Spanish dates to the early 1700's, when they were convinced to move south into Florida to act as a buffer against British and French colonials. Until then, the Miccosukee had only been into Florida on hunting trips... they never lived there until after 1712 or thereabouts.

It would have been better to move the town location down the west coast of Florida and name it "Caloosahatchee" after the dominant tribe in the area, with the most developed civilization and largest towns, and in memory of Ponce de Leon's contact with them.
