  Sorry, I had no time (and no clear way to express things) when what
  I’m going to write could have been more relevant — anyway, this is
  about SignWriting.

I consider the precedent of SignWriting as an especially bad model to
become a base for other encodings of extensive collections — and not
since it uses “many mechanisms”, but FEW mechanisms. I think that the
same functionality could have been implemented using a tiny handful of
new characters — while making the encoded SignWriting text readable
EVEN WITHOUT SPECIAL FONTS and/or shaping engines.

See, for example, the Mr Potato Head font
  http://www.unicode.org/mail-arch/unicode-ml/y2014-m09/0003.html
; using the same principles, one could encode most (all?) of the hand
symbols as
   SignWriting FACE STARTER CHARACTER + upper/lower-script modifiers
For example, hand with fingers 1,2 extended, 3,4 crossed, and 5 bent
halfway could have been encoded as
   ☆¹²³ˣ⁴⁵ᶜ

A specialized font would show the needed glyph. Without a specialized
font, one could see a representation which allows one able to
visualize the shape — and, at least, see a certain distinctive
rendition.
  
As far as I checked (about 60% into the SignWriting proposal) this
approach would enable all of SignWriting functionality with about 10
base characters needed. As for rotation modifiers, we already have 24
(?) clock face symbols — and they allow granularity of 15° when
specifying the rotation.
