In a Blackwood sequence, a player bids 5 in response to the 5NT enquiry. Is 6 a comparable call?

(1) 4NT is simple Blackwood, a 5 response to 4NT would show two aces and a 6 response to 5NT would show two kings.
(2) 4NT is RKCB, a 5 response to 4NT would show two key cards without the queen of the agreed trump suit and a 6 response to 5NT would show two kings (ignoring the king of the agreed trump suit).
(3) 4NT is RKCB, a 5 response to 4NT would show two key cards without the queen of the agreed trump suit and a 6 response to 5NT would show either (i) One king - the king of hearts or (ii) Two kings - but not the king of hearts.

Thanks

I would allow any of them under the "same purpose" clause. Should it turn out they have gained from it, we still have 23C in our armoury.
