Just to avoid confusion, `org-emphasis-alist' is not designed to change 
or to *add* new markers:

If you wish to export =verbatim= text as text with line above, perhaps, 
you can define custom "verbatim" export filter
"info (org) Advanced Export Configuration"
https://orgmode.org/manual/Advanced-Export-Configuration.html

A macro expanded with markup for particular backend (e.g. @@latex: 
...@@) may be a better option
"info (org) Macro Replacement"
https://orgmode.org/manual/Macro-Replacement.html

Some people experimenting with custom link types with associated 
handlers for particular export backends:

Unfortunately you described what you have tried in too general words to 
suggest something more specific.
