I have something like the following. Maybe you could roll something like this 
for your needs.

(defun mm-toggle-tex-pdf-viewer ()
  (interactive)
  (let ((viewer (read-string 
                 (concat "Current PDF viewer: " (cadr (assoc 'output-pdf 
TeX-view-program-selection)) "; change to? ")
                 nil nil
                 '("Evince" "PDF Tools" "zathura")
                 nil)))
    (setq TeX-view-program-selection (assq-delete-all 'output-pdf 
TeX-view-program-selection))
    (add-to-list 'TeX-view-program-selection (list 'output-pdf viewer))))


Best,
Mandar.
