A new way to open weak NT in Acol Is this just mad?

Suppose when we open 1N we guarantee a 4/5 card major and 12-14 hcp, those hands that no longer qualify get opened 1♣ or 1♦
We can use 2♣ as 5 card stayman with a 2♦ response denying a 5 card major and the rest of the 1N responses can be as normal
1m 1M 1N would have to be 12-17 with 2♣ as checkback
Obviously we lose some preemptive value, but I think that some of the additional inferences that can be drawn from the bidding might be interesting. I do not know if there would be any value in doing something similar in strong NT systems
Thoughts?

How are the minor suit openings supposed to work if they have to cover 12-19 balanced as well as unbalanced hands?

They have 4 cards in the suit opened and the rebid of 1N will cover the balanced hands 12-17. It is no worse than a 1 minor opening in sayc imo

I would have thought it was still inappropriate: assuming traditional 1NT opening criteria, there is slightly less than 50% chance of opener holding a 4-card major, so more than 50% chance of playing 2M in a 4-3 fit when most of the field is in 1NT.
Looks to me as if responder's majors have to be at least 5-4 in a weak hand for this gadget to be worthwhile.

And it might be easier to defend contracts played by your 1NT opener when he is known to hold 4 cards in one of the majors.

In sayc the rebids are
1n 12-14
2n 18-19
You could maybe put all the balanced hands w/o 4M in 1c and then play some artificial responses

With a hand like ♠xxxx♥xxxx♦xxxx♣x opposite a 1NT opener, Stayman is an entirely appropriate bid.Indeed its the only sensible one in the present circumstances(!) Imagine having to play 1NT facing that collection of junk as dummy(?!)

Somehow I feel you're replying to a sentiment which hasn't been expressed at any point here, Phil.
The shape of the hand was specified in the op, with a singleton diamond. In that case Stayman on a weak hand is inappropriate, unless (as nullve said) they play crawling stayman.
No one here was suggesting you need invitational values for stayman; I hope that's cleared things up.

SAYC the 1N rebid is 12-14. To suggest a 6 pt range of 12-17 won't create problems is simply uncredable.

If opener is 2245 or 2254 or maybe some others, they just take a bad board.

Sir,i fully agree with all who said that rebid of 1NT.shows 12/14 HCP.It is just unthinkable to play it as 12/17. a 2NT rebid also shows exactly 18/19.AND in all probability the rebid of 3NT would show exactly 20 as with 21/22 or even GOOD 20 the hand if balanced would be opened 2NT.Even any strong club with 15/17 NT system shows only 12/14 HCP when the rebid is 1NT.Lastlly even in Precision system an opening bid of 1D followed by a rebid of 1NT shows exactly 12 HCP as with 13 /15 HCP the hand is opened 1NT. Therein also a rebid of 1NT cannot be stretched to 12/15 HCP.

You seem to assume that playing 2M on a 4-3 fit when the field is playing 1N is almost as bad as playing 1N when the field is playing 2M on a 4-4 fit. I don't think it is.

Personally, if I open 1NT (12-14) I'm in general denying a 5CM. Otherwise I would open that major (there may be exceptions - say if my major is Jxxxx). So I expect a Stayman response to be asking for a 4CM. And (although partners have disagreed with me on this), for me Stayman can be weak, and I can pass the opener's 2♥ or 2♠. Am I wrong about this?
I was certainly told off once when I opened 1NT and it went 1NT - 2♣ - 2♦ - 2NT - pass. My partner told me his 2♣ was GF. I could only apologise . But - in retrospect - if he had the values for game (knowing I hold 12-14) why doesn't he just go 3NT?
The other point is that I would open a 4CM on 15+ points. The idea being to bid 1NT or 2NT on the next round. Seems commonplace bidding to me.

We play 15-bad 19 1N rebid in a weak NT context and it's fine, you can deal with big ranges (I've also played a 6 point range on an opening NT but that needs special methods to make it work well).
I've seen the reverse in a weird artificial club system where 1♣-1♦-1♥ is a weak NT with 4 hearts and the 1N rebid and opener are bigger.

As Nullve states, when responder to 1N has 4+4+ in the majors, a 2♣ reply is fairly safe, with appropriate garbage-Stayman agreements, e.g. after
1N - 2♣ -
2♦ - 2♥ -
??
If you pass with 3♥ but correct to 2♠ with 3-2 in the majors, then you play in a 7+ fit,

Till partner perpetrates one on 2-2 majors. We do this, but no guarantee, one of the best bits of play of my life was convincing both defenders that I had a third trump so they couldn't simply draw trumps and claim, converting -1700 to -800, still cost IMPS.
