It will depend to some extent on what type of inaccuracies there are. If it's just the primary xy coordinates that are off, then you should be able to correct for that (although with some potential undersaturation issues). There are any number of other possible problems you can run into, though, such as incorrect secondaries, inaccurate color decoding, etc. Some of these require more sophisticated correction than what's needed to just move the primaries.
One related problem, though, is the one you mention - i.e., a limited number of bits of resolution. If you only have 8 bits of resolution to work with, then adjusting the primaries will reduce the effective bit depth available, and will also potentially cause visible banding issues. If you're working at bit depths of 10 or 12 bits, the banding problems should pretty much be a non-issue. That higher bit depth has to be present through the entire signal path from the Lumagen to the display's imaging element itself, though, or you're likely to just re-introduce the problem at a later stage.
