Not tested, but looking at the code above this is the expected behavior
since you overwrite the value of `LaTeX-math-list' before the
`LaTeX-math-initialize' call.  Try something like this:

--8<---------------cut here---------------start------------->8---
(eval-after-load "latex"
  '(progn
     ;; Remove default <g> binding.
     (setq LaTeX-math-default
           (delq (assq ?g LaTeX-math-default) LaTeX-math-default))
     ;; Clear and remake keymap.
     (setq LaTeX-math-keymap (make-sparse-keymap))
     (setq LaTeX-math-list
           '(("g a" "alpha" "Greek Lowercase" 945)
             ("g b" "beta" "Greek Lowercase" 946)))
     (LaTeX-math-initialize)
     ;; Bind new keymap.
     (define-key LaTeX-math-mode-map
       (LaTeX-math-abbrev-prefix) LaTeX-math-keymap)))
--8<---------------cut here---------------end--------------->8---

Ok, thanks for your comment.  Can you please elaborate why the math mode
is clumsy?
