CXS and IPA symbols for uvular approximant

BTW has there been any proposal for a symbol for
an approximant [R] distinct from a fricative [R]?
I suppose differentiating between U+0281 LATIN
LETTER SMALL CAPITAL INVERTED R and U+1D1A LATIN
LETTER SMALL CAPITAL TURNED R won't do (and how to
find a CXS for that?) so I hereby propose U+01A3
LATIN SMALL LETTER OI = LATIN SMALL LETTER GHA
with CXS [q\] for the voiced uvular approximant.

The Sohlob "q" very definitely is [q\].  The Persian
sound transcribed "q" seems to be (fricative) [R] and
even [G\] sometimes.
