This should be possible with `org-e-beamer-environments-extra', i.e.

  (add-to-list 'org-e-beamer-environments-extra
               '("onlyenv" "O" "\\begin{onlyenv}%a" "\\end{onlyenv}"))

Then you set headline's BEAMER_env property to onlyenv and modify
BEAMER_act accordingly.

These attributes modify the whole list. To set overlays for individual
items, use export snippets. Examples follow:

  #+ATTR_BEAMER: :template "i)" :overlay "<+->"
  1. First item
  2. Second item 

will become

  \item First item
  \item Second item


  1. @@e-beamer:<1>@@ First item
  2. @@e-beamer:<2>@@ Second item

will become

  \item<1> First item
  \item<2> Second item

Again, export snippets should allow this. To obtain:

  \item Anode \tikz[na] \coordinate (s-anode);
  \item Cathode \tikz[na] \coordinate (s-cathode);
  \item Saline bridge \tikz[na] \coordinate (s-bridge);

You can write:

  - Anode @@e-beamer:\tikz[na] \coordinate (s-anode);@@
  - Cathode @@e-beamer:\tikz[na] \coordinate (s-cathode);@@
  - Anode @@e-beamer:\tikz[na] \coordinate (s-bridge);@@

I think so. Have you tested them?

Thank you for testing the back-end.
