this is where I hoped this discussion would go

At the table I'd probably give up on 7 and bid a direct 6♠ over 1N.

If you play 4♥ after the splinter as a cue then you have to find another bid, IMO possible instead of 4♦ but if you do bid 4♦ then you have to kick with the North hand. Maybe just

 

Pretty sure I'd use a gadget to ask partners shape*, upon hearing 3343 I'd bid 3♠ to set trumps which invite cues hear the ♣A and roll out RCKB find 2 aces and 1 king & no Q♠and bid 6♠.

 

*The gadget is a transfer to ♥ followed by 2♠ to ask shape, pards bids 2nt with 4333 - 3c asks which suit, or the lowest of suits with 44 - again next suit up asks, if he has 5♣ or 5♦ then he bids 3♠ or 3nt.

 

It means you don't open 5-Majors 1nt which is a little drawback and with a maximum and good ♥ you superaccept the transfer as if you are responding to 2♠. It has downsides but I like it as it can find a pushy minor slam and allows 3nt as a spot to play when you are mirrored, which though rare does make you smile when it happens for a good score.

1NT-4♥

4♠-4NT (rkcb in ♠)

 

 

At the table I'd probably give up on 7 and bid a direct 6♠ over 1N.

 

I think splinter is definetelly needed on thishand, since that´s the way you can find a good grand. I don´t understand the urge to blast

The reason to blast is that if you do happen to catch partner with Qxx, Kxx, AKQJ, xxx you may stand a much better chance of making 13 tricks rather than 11 in 6♠ than if you've bid it scientifically.
