Um, just stumbled upon this concept on DeviantArt — interested in finding out who the Caf's resident One Piece readers/watchers would select for their “crew”...

Did this on my phone, so I'm all over the place with editing.
I'm assuming non-pirates like Megallan or Akainu are off the table. I also assume Aokoji isn't allowed. Can't remember if Shiki was a Yonko, but I'll just think of him as too op.
I'll go for a serious bunch of combat specialist, if possible my utility people will also have some use in fighting.
Combat: Katakuri (lookout) Marco (doctor), Zoro, Law (surgeon), Mihawk & Rayleigh.
Utility: Nami (navigator), Jinbei (helmsman), Caesar Clown (scientist), Robin (poneglyphs), Crackers (does all the work a normal crew would do) & Sanji (chef)
Combat:
Katakuri for future sight, Marco because he is op, Zoro mostly because his attitude is welcome & partnering him with Mihawk would give him a platform to rapidly power up on. Taking Mihawk is a no-brainer. Law has a seriously hax ability that can help take down big guns if needed while his room can help take out large portions of fodder, he also offers the group some movement when it's needed. On top of that there is the off-chance for eternal youth.
Rayleigh for his experience and help to teach the others who may not understand advanced haki.
Utility:
My role: Chef & captain, chef seems the easiest job on the ship, and I think it would be fun to experiment.
Devil-fruit: Rumble Rumble Fruit (Enel)
Nami seems to be a proper navigator, and her stern view on money is very welcome so we don't feck about too much or we go into the trap of being too kind to take rewards or gifts.
A fishman at the helm is just natural. I also need some swimmers in case something happens since I plan on having a devil-fruit.
Caesar as a scientist as he functions as a combat & science guy at the same time.
Franky for shipwright. Good attitude & knows the secrets to Pluton.
Robin is needed if you want to learn everything without just hearing it from Rayleigh.
I'm taking Cracker for the boring tasks as his soldiers can do a feckton of work without getting tired.
The last spot goes to Sanji, because I'd rather be the secondary chef/assistant than the main one.
