TBF you have 12 without the heart jack, but you need the club jack, if the weak hand does the asking (not quite sure how you engineer this) with both QJs, if he can find out about 2 AKs and the other 2 Ks he can bid it, but if the big hand asks it's well nigh impossible to be sure after a muiderberg.

South has 9+hcp and initial thoughts on getting to the slam
After a 3♠ cue, I play 3NT denying 2♣ honours which may be passed.
North shows an odd number of keycards, a ♣ honour and ♥ control with 4♥
If South now bids 4♠ North can deduce a void meaning South must have Q♣, AQ♥ and at least 1 Jack.
