Does anyone think the Bluetooth module supplied with the Hexy will work with the 3.3v TX RX pins of the Due?
I read the supplied datasheet which mentions 3.3v logic. I had difficulty deciphering the Engrish and wanted to see what others think.

Not an EE nor even close to being an expert.
But, I have messed around a fair amount with this chip. The chip itself is 3volt TTL on a logic level board (not the correct term). This logic level converter board lets you use a 5volt serial (like from your Arduino) to talk to the Bluetooth chip (CSR BC417). That said, if you tie all your grounds together you could just bypass the logic level converter board it’s soldered too and talk directly to the BC417.
This has been one of the better posts for the CSR BC417 chips and Arduino. It’s a great cheap versatile little chip.

Side note, learned all this by making a remote control (Arduino) for this toy.
