What should the Beast Pirates ' flagship have looked like ?

One of my many disappointments with Wano and how the Beast Pirates were handled is that we have never seen the flagship of the crew, Kaido's personal ship even if as a dragon he doesn't have an use of it most of the time but it's still a symbol of his crew and something he should have had when the Beast Pirates were formed and when they arrived in Wano, plus we have seen the flagships of the other original Emperors, as well as ships of arc antagonists such as Arlong or Doflamingo's in flashbacks even if they weren't used anymore in the present.

How should Kaido and the Beast Pirates' flagship have looked like ? What kind of ship should it have been and with which design ? How huge and well-armed should it have been ?

And what would be the best name for a ship captained personally by Kaido ?
