Logically this seems like the right treatment, but I am always afraid to just spring it on my partners without previous discussion:

(P) - 1 - (P) - 2
(P) - 2 - (P) - 3NT
(P) - 4- (P) . . . .

or (leaving out the OPPs' passes this time):

1 1
1NT 2
2 3
3NT (or 3 ) 4 . . .

Logically these and similar auctions seem like minor suit slam tries and 4NT should reject the try and suggest a contract, not ask for Aces. Still, without prior discussion . . . .

Taking 3NT out into 4m is almost always a slam try (exceptions tend to be obvious). How one proceeds thereafter is a matter of agreement. For example, it would be perfectly logical to use 4 as the negative on auction 2 rather than 4NT.

Auction 1 is trickier to comment on as you have not told us the system nor whether 2 promises 5 or not. If 4 agrees diamonds then it is logical (to me) for 4 to be a negative. If 4 is merely patterning out then we probably need 4NT for this and 5 becomes Last Train. It is also relevant what 4 instead of 4 would have been.

Happy New Year everyone!
