Not really.  The 3-digit hex works by duplicating each digit in-place.
 The 1-digit hex would sextuple the single digit in-place.  (One could
also argue that 1-digit hex uses the same expansion rule as 2-digit
hex, and one would be right.  It's a degenerate case.)

2-digit hex, if it used the same expansion rule, would expand #12 into
#111222 (which is obviously useless).
