Can you rely on Edition 6?  I may have misunderstood your goal which I
took to be a request for minimal sized objects.  If you don't mind
wasting bits, there are lots of ways to do what you ask (see other
replies prompted by my "no" reply for some examples).  But these new
types only give you another kind of container into which to pack the
data -- they don't allow you to do anything you could not do otherwise.
