While anything's possible, and hurricane intensification forecasting is more black art than science, I'd have to say that I doubt a repeat of Camille (or even Katrina) is likely. Mainly, because Camille spent about 48 hours in the GoM after crossing across Cuba. Gustov will spend less than 36 hours before hitting W of NO. Those extra 12 hours in 88
o F. GoM waters would make a universe of difference to Gustov.
My target has been Lake Charles area, but farther E, e.g., Vermillion Bay is quite reasonable.
