I think if you are worried about specific holdings and shape, you should just accept the 6n contract (which was in line with the rest of the room) and move on. Playing some kind of relay system is realistically the way to get to the grand. With standard systems, you're just guessing.
It's one of those positions that without a relay it's almost impossible to be exact, basically if N has
♣Ax you may be in a no play grand, if he has Axx then it's 100%, depends how you feel about that (and
♥J would give you an easy potential out that you're not going to find out about).
Basically to get there with certainty N has to treat his hand as single suited diamonds rather than balanced despite the poor suit, ask, and find out about S's 6 high cards, which is difficult.
We have a shot, the auction would have to go:
1
♦-2
♦(10+, 4+
♦, doesn't deny 4M)
2N (15+ balanced or diamonds, GF)-3
♣(art enq)
3
♦(single suit
♦)-3
♥
3
♠-4
♣(A/K)
4
♥(Kickback)-5
♦(2 with)
5
♠(K)-6
♣(Q)
?
Now the question is whether 3
♥ would ever be bid without
♥K, N can count 12 tricks plus the probable
♥K, 3
♥ can be just a stop.
If N signs off in 6
♦, S can bid 6
♥ on the way to 6N and find partner bids 7N, if N bids 6N this will end the auction, N could just punt 7
♦/N.
