I've done exactly this in any number of situations. Enumerations are
definitely "The Ada Way" of solving this problem, so naturally you want
to try to do this. However, if you're suffering a memory penalty - and
using Ada83 - there is no "conventional" way I know of to turn off
storage of all the stuff you don't want. But most embedded compilers
give you some means of doing this anyway - you need to tell us what
particular compiler you are using.

If you can't find an answer in the compiler-specific documentation, you
can always get there through the
less-desirable-but-no-worse-than-C-does-it method of declaring a bunch
of named numbers:

Some_Name : constant := 2#0101# ;

It does, as you observe, have name-space problems, but it will get you
there. I'd still urge you to check the compiler documentation (and let
us know the Manufacturer, Host, Target and Version - if possible because
someone else has probably been there already) because this is hardly a
new problem and is something most vendors accounted for in some way.
