collapsible excerpt-reloaded, please

On my main page, I show full posts. On archive pages, I use the_excerpt Reloaded plugin to show excerpts with links to the full posts.

What I would like is for the excerpts on archive pages to be collapsible / expandable, along the lines of the inline (collapsible) more link plugin.

Is there a way I can tweak one or both plugins to do this?

Thanks!
