I don't think any of our current players or prospective players are worth consideration for a "Big 3". IT is a one-way player (although, an extremely effective one-way player) and Horford is not an all-star (I'd argue that he never should have been an all-star and simply made teams due to a weak conference and his designation as a center). If Hayward were to sign here, he's also not on that level yet. There's a clear tier where players like LeBron, Durant, Curry, Westbrook, Harden, Leonard etc. belong and where guys like Hayward and IT belong. It's just not the same level of talent and impact on a game.
