2♦ is ostensibly negative, but we tend to hate the 2N response and won't bid a 5 card heart suit as bad as this.
Do you go on ?

2♣-2♦
2N(23-24 bal)-3♦(♥)

How do you think the auction should proceed opposite AQJx, Axx, A, AKQxx ?

2♣-2♦

This hand by our methods requires a little thinking outside the box as we play 1N-3any as forcing and one suited, and stayman followed by 3minor as to play, so while we can get the hand across, it would take some imagination to do.
Our auction should have been:
1N-2♣(stayman)
2♥-2♠(minor suit stayman, at least marginal slam invite, may or may not have spades)
3♣-3♦(must show 5 as partner 4-4 in ♥/♣, and by inference 4♠ from the stayman)
4♦ and onward to a slam
