I think that this would be a splendid thing, which would make for much better immersion and make carriers actual.. carriers.
Plus as Tenacity says, it's not like launching 4 high level fighters would create that much lag.. it's not like everyone and their mother are flying a Carrier. They're very costly you know.
So yeah. Launching NPC wings, yes!
