We have Four Emperors + Man With Burn Scar,
We have Sukiyaki, Robin, Vegapunk, Pudding & Moria,
SHs already have Robin,
Blackbeard have Pudding,
Now Cross Guild, Shanks & Man With Burn Scar must Pick from Remaining Three,
Assuming Man With Burn Scar doesn't target Land or Sky, then Moria might End up with him,
Which makes me more Convinced that that Black Ship is indeed made for those who once reached Greatness & then Fell Hard,
Such as Moria, Kid, Magellan, Shiki ... etc
