NO, shika will not become stronger if Chouji died. Shika's lazy, he doesn't want to train. Why would it take someone's death in order for you to sincerely train? That and he admitted that he just wanted to become a regular ninja, with a regular women, to have a regular life.
Also consider that since Chouji is his best friend, he may spiral into depression. Since he wasn't strong enough to help him. It was his decision, his and his alone (since he was team leader), to have them fight one on one. He may be guilt ridden and stop training all togeter.
