Could a giant join Luffy's crew? Is BB the only current crew to have a giant? Could a giant live inside Bege?

It seems no crews have a giant member (pause).

Is there a way to fit a giant in a ship? I guess Sanjuan walks behind BB's ship, since he's so tall. Most giants are too small to do that. Even Loki may be too short for it. So who can get a giant on board?

Bege could store Loki inside him?

CP9 could recruit Loki, if Loki stays in Blueno's dimension. They can give him an abacus, some megablocks (lego is too small) and take turns keeping him company. Maybe it won't work, if he still needs to move at the same speed and in the same direction as the ship to keep up.

Law could chop Loki up. Then keep him in a special cupboard for later reassembly. Keep his head on deck.

I don't see it. The future king of the giants is already part of their grand fleet at least.

What if Usopp never lost weight and was still a giant during Part II?
