I like the idea of 4NT specific A ask, but if partner has a round king, I am not sure what call I can make that says "find me another King please".
In my version of the 4NT ask, a 5
♣ reply shows
♣A or no Ace (5
♦ asks). Now 5NT is a specific King ask (to sign off in 5NT or higher opposite no Ace, go through the ask of 5
♦ first), with 6NT as negative reply. If the Specific King reply is 6
♣ or 6
♥ then cue 6
♠ asking for that King, which will elict either a positive 7
♣ (so bid 7NT) or a negative 6NT (so pass).
It's not a frequent situation, but not much memory load either (if you already play cue over Specific King when trumps are established).
