Oh take your head out your ass, I've already shown it works. Its a good way to avoid getting jabbed out.
Yet you also mentioned this.
I can't speak for V but in 3S grabs only land by crushing strikes.
This is the big problem with you. You're speaking as if you're some sort of be-all expert on 3rd Strike, when you clearly aren't.
There are other, more useful ways of landing throws in 3rd Strike. Kara throw, dash up throw in neutral, tick throws, and of course, throws off parry option select (e.g. SGGK). Heck, the last one works in that the throw doesn't come out if they hit an attack (but does if they sit and do nothing but block).
Then, there is the fact that "crush" as used in DOA actually doesn't exist here. It's all about interactions with the hitboxes and frame data. Throws tend to beat out jabs in 3rd Strike due to a combination of longer range and faster frame data.
That said, for a throw to connect, its active hitbox must connect with the vulnerable hurtbox of the opponent. However, it's also possible to set it up where the throw won't connect with the vulnerable hurtbox, but still hit the opponents active hitbox, which will result in the throw being hit.
