We have vessels which can transport landing craft and the like (LHA-8 and beyond have well decks restored to the design). How about such vessels equipped with squadrons of modern day PT boats or even drone attack vessels? While the LCS concept seemed good, in execution, it's like the railgun --looks good but too expensive and unreliable, and stripped of capability by the expense.
In the future, such designs could be the 'mothership' for both airborne and surface (and even subsurface) drones.
