Wouldnt it be hilarious if the marines were all in the same pirate crew. u always see akainu yelling at kizaru and aokiji for being lazy and doing everything half-assed. and whenever they battle another crew akainu,aokiji,and kizaru would always use thier powers while on the ship and always damage it. when that happens sengoku would yell at them and garp would just laugh and sengoku would yell at him too while all the other marine pirates would cower in fear. finally, u would always see smoker looking out into the ocean and thinking to himself on how he got into this mess(crew).
