sorry, gwnn wrote what i wanted to say but i wanted to point out its good to bid puppet stayman with 42 majors as well as 43 and 33
In case we want to play our 5-2 fit?
Is 1NT-3m = 6 card minor nothing else a good convention?

It's an issue of information revealed in choice of game auctions, jlall wrote about it here

Also, you wouldn't bid puppet stayman anytime you were going to follow up a nonfit response to stayman with 3m.

It's certainly a common treatment when playing a weak (12-14 HCP) notrump,

Two example of where Puppet Stayman gives less information about declarer's shape than regular Stayman:
1NT - 2♣; 2♦ - 2♥; 2♠ - 4♠. Here it is unknown if declarer has 4 hearts or not.
1NT - 2♣; 2♦ - 2♠ (hearts); 2NT. And here it is unknown if declarer has 4 spades.
In both cases more about declarer's shape is known after a normal Stayman sequence. Of course Puppet often reveals more about dummy's shape. It is actually more efficient to use 2♣ as puppet and a following 3♣ as GF regular Stayman than 2♣ as Stayman and 3♣ as puppet. However, that approach exposes you to lead-directing doubles much more often than the methods Clee describes and requires more artificiality/complexity.
As for the OP's proposed convention, I have to say I am not a fan on first look. If the point is to make 3m passable then that is going to be extremely rare when the shortage is unknown. And checking on the shortage is necessary after 3m; no doubt you have follow-ups to allow this but can you also stop in the right contract afterwards? And what about when Opener has a perfecto - if 4m is also non-forcing can we have a sensible slam auction? If the answers to all these are yes then sure; if not then I would need some pretty good test results before throwing it into any system.

Me and my live partner choose to play @ MP..
2C 6-8 HCP stayman (or a 9-10 which may have trouble with NT) (used @ MP gambling to find a suit fit over weaker NT)
--2D shows H(can have S)
--2H shows S(no H)
--2S shows none with minimum values
--2N shows none with maximum values (inviting)
2D ♥transfer
2H ♠transfer
2S ♣|♦transfer -> 2NT waiting
2N ACE ?
3C 9+ HCP stayman (GF)
3D 9+ HCP 5/4 ♥/♠
3H 9+ HCP 4/4 ♥/♠
3S 9+ HCP 5/5 ♥/♠
3N STOP
4C ♥transfer (slam invite)
4D ♠transfer (slam invite)
4H STOP 7+♥
4S STOP 7+♠
4N 5/5 ♣/♦ (slam interest)
Works very well for us...although I am sure some of it could be done away with for better alternatives.
