I agree with your thoughts, but not sure which one...?
There are several Genera of "Giant-Skippers" and Megathymus is the best known (several described species and numerous geographic forms/races). I'm inclined to think this is one of the Agathymus or possibly Megathymus, but the ventral surface is much more frosted and patterned than any I have ever seen.

Refer to the following:
Hesperiinae (syn. Megathyminae / sometimes split into the Family: Megathymidae), Tribe Megathymini J. H. Comstock & A. Comstock, 1895
