The short answer is yes you can use a jeep carrier or any carrier. BUT... We only use them two times per year at Nationals as convoy ships. You might get 10-20 min of run time out of that work. Much better to start with a cruiser or battlecruiser. They have guns CVs don't
I guess a CVA could have a couple guns but I have to agree with Bob, if you want to battle there are better options.
