I do not think this is needed.

The existing markup is simple and useful and does not complicate the 
appearance of the org buffer nor editting it.

More complicated inline markups can be rendered with export snippets, 
macros, and/or inline src blocks. For example:

--
#+MACRO: code src_code[:eval no :exports code]{$1}

{{{code(y~x)}}}
--

will handle many situations.

If one needs to render something with embedded commas and/or backslashes 
like

: y~x(z,w)
: cat("here is a newline\n")

then

: src_code{ y~x(z,w) }
: src_code{ cat("here is a newline\n") }

works if `org-babel-default-header-args:code' is

: '((:eval . "no")(:exports . "code"))

HTH,
