Thanks for the list; it is an interesting
suggestion.  Back when I was working with 11SD
and 15SD we were after dodecimal (eventually
hexagesimal) numerals and hex numerals.  The
approach then was (obviously) incremental: each
successor number got a numeral with one more
segment lit (keeping all the old ones).  One
upshot of that was the recognition that radically
different shapes rather than just added
complexity made for more recognizable characters.
 We were able to combine the two fairly well by
adding segments in a way to make each successive
character markedly different from others, though
not alwys different enough.  Taking those
principles to 7SD (and adding binary numeration
rather than simple count) gives, for example, the
following (in standard alphabetic form and my
decimalized binary) 0: G 8 (always on to provide
a frame of reference for the other lines)
1: BG 40 (reversed upper L) 
2: CG 36 (flip of above, 
3: BCG 44 (right turned T), 
4: FG 24 (upper L), 
5 BFG 56 
(upper square cup), 
6 CFG 28 (left to right zig), 
7: BCFG 58 (standard 4), 
8 EG 10 (mirror of 2, flip of 4), 
9 BEG 42 (right to left zag) 
A (10)CEG  14 (bottom cap), 
B (11) BCEG 46 (mirror h), 
C (12) EFG 26 (left T), 
D (13) BEFG 58 (mirror 4), 
E (14)  CEFG 30 (h), 
F (15) BCEFG 62 (H).

Of course, many other patterns along this line
will work, including just using the bottom square
  CDEG (1,2,4,8) or the upper square, though both
of these have problems with single lines floating
free.
