I see the OP asking 2 main questions.
1) is 5431 and 4432 a 3 suited hand...I showed evidence it is not.
2) is it GCC legal to play 2clbs to show any 5431 or 4432. I don't know..It would be nice to hear from some current ACBL directors on that question. I was last a director in the early seventies.
If I had 26 cards in my hand, I'd call the director.
From the GCC:
Quote
3. TWO CLUBS ARTIFICIAL OPENING BID indicating one of: a) a strong hand. b) a three-suiter with a minimum of 10 HCP.
5. TWO DIAMOND ARTIFICIAL OPENING BID indicating one of: a) a strong hand. b) a three-suiter with a minimum of 10 HCP.
Given that these two rules are identical, and given that opening 2
♦ in Precision on (43)15 is legal, it seems very unconvincing to argue that opening 2
♣ on a similar distribution (I gather that the singleton could be in any suit, but I hardly think that matters) is not legal. Either way, I would not call 4432 a three suiter, or even a two suiter. Calling a hand any kind of a "suiter" implies that you think it is better to look for a suit fit than for a NT contract. For me, if opener has a balanced hand, he should show a balanced hand. I would also say that trying to add "or a balanced hand" to your 2m opening would mean it does not fit whichever of these rules you're trying to apply.
