Christopher,
This is an excellent suggestion. A submission can be made using
n2352-form.pdf that you can get from this site.

Subject: Chinese rod numerals
>
> I am an academic with research interests in the history of ancient
> Chinese mathematics, and I should like to propose the encoding of
> traditional Chinese rod numerals.
>
> These represent the arrays of "counting rods" on a counting board as
> used in China for complex calculations before the invention of the
> abacus. There are eighteen forms in all, representing the numerals one
> to nine in two forms which are basically versions of each other with a
> 90 degrees rotation. One form is used for units, the the other for
> tens, then back to the first form for hundreds, and so on. A zero is
> represented by a gap in the array. For pictures of these and an
> explanatory text, see:

>
> These forms appear in pre-modern mathematical books in China, and in
> modern books discussing ancient mathematics. They are not to be
> confused with the the related "Hangzhou numerals", which are already
> encoded at 3021-303a. It would be a great convenience to have these
> as a standard resource rather than having to create a special private
> font in order to represent them.
>
> From a private source, I have been told that these forms are neither in
> any current Unicode encoding initiative, nor indeed anywhere in the
> proposal pipeline. I should therefore be grateful for any comments or
> advice that might guide me towards making a formal submission.
