Given that carriers are increasingly boxed out from shore by anti-ship missiles and drones are a lot smaller than crewed aircraft, I wonder if this design concept is due for a revival.

I could imagine drones launched vertically with single-use rocket boosters that would then land on the water for retrieval. You could get much closer to shore than a carrier while still carrying out a pretty effective air strike, especially with several subs.

Reusability creates a lot more complexity vs just cruise missiles. Current generation US attack subs have multi-purpose tubes that can launch underwater drones, etc. So they are designed for some flexibility, but the main use is just tomahawk missiles.

Apart from the "reusable" part, your proposal sounds a lot like cruise missiles, which subs can and do launch. True, reusable is nice. But a cruise missile can also carry a lot bigger payload than a reusable drone can.
