Some of that 6gig is lost in the formatting, 16Gb is the unformatted space. The system partition will remain the same size. However if you use something like "Nandroid manager" from the play store you can restore apps from the nandroid so you shouldn't need to back them up in TB, you could save space by just backing up the most recent data for your user apps
You do have the option to convert user apps to system apps in TB so you may want to play around with that. I'm "assuming" that will move them from the data partition to the system partition. Im not 100% on that but you could always just move one and check.... Having said that the apk's themselves are usually relatively small, its the data stored in Android/Data that usually account for most of the install size.
Few ideas there for you anyway, other that that your obviously better off with a 32gig version. After my apps installed, 1 Nandroid, some local music, and user apps backed up in TB I have approx 15gb free.
