Obviously the Europeans would want a european solution
I think the A400M would be way to big & expensive. A bombbay seems problematic. Much of the systems could be used, e.g engines.
A while back I sketched a euro concept that can transfer fuel to other MPAs and helicopters, as well as move 20 people/ cargo and carry optional gun turret (counter piracy). Single purpose platforms proved risky in dynamic times.
