Part of the Gremlins challenge was the characterization of the aerodynamic environment in the highly turbulent area behind the ramp or the wings with the flaps down or and the props operating. Securing the Gremlins in all degrees of freedom prior to stowage is going to be harder than the single point type of contact of aerial refueling.
Presumably the carrier C-130 could be manned and any hard contact cannot be tolerated.
In complete agreement and that is why this concept has never had military utility. If the payload is so sensitive that it must be returned then use a different UAS. Manned transports vulnerable to S-400 S- 500  ::)

An expendable drone, small enough for 4 of them, able to be carried internally by an F-35 would be something to consider. Dropping 4 of them into the battlespace each with 3 to 4 hour endurance would be really awesome. When they're done, then dive bomb into a target or into the ground.

Something like a smaller tacit rainbow in size.

...or maybe 24 of them in a Bone is a better idea?
Yeah, it is called all various versions of MALD since forever.

No, not unless it somehow magically fits inside and F-35 now.

Even if recovery proves to be an occasional thing you're still ending up with an expendable
with more flexible, heavier payload than MALD and (potentially much) longer range.

Provided that the recovery equipment doesn't displace some of the volley payload...

The 'flying coke machine' concept is one thing and would likely still need to be jet able to survive while recovering multiple large semi-attritables is another and questionable. Allowing a adversary to chase your rabbit back to its nest  ::)
