Could use some Team Advice

So basically like the title says i could use some help with my Team.
I've been mainly focusing on getting a Slasher team and here's my current team:

Enraged Arlong lvl 52 (Captain)
Ashura Zoro lvl 25
Kuro lvl 47
Diable Sanji lvl 16
GP Usopp lvl 32

now my plans are to get Vista and use him instead of Sanji, since he's a slasher with the same 5k atk all special skill that Sanji has.
And also id like to get Mihawk (obviously) and make him my captain..so Intended Future Team:

Mihawk (captain)
Enraged Arlong
Ashura Zoro
Vista
GP Usopp


so really my questions are
1: is this a good team to try to go after?
2: Can i beat the 30-stam mihawk island with my current team? or if not what are some simple things i can do to improve my chances

Also i should note that my ship is a lvl 1 Baratie (waiting on the Marry that can fly to use all my cola on)
and im also currently spending my time farming Twin Cape CH. 5 to try and get Vivi, because i heard she helps against mihawk.

Any suggestion/ advice would be welcome

Don't think thats enough for Mihawk. You have to use laboont to defen the 40 Stamina Stage and get Mihawk 100%. And one team is for me not enough

1. Nothing wrong about that team, would use an evolved Mr. 3 or vista if you can get them.

2. Your team's levels are really low, definitely cannot take on 40 stamina, but you might be able to take on 30 stamina with a g3 luffy guest captain. Would probably be better to run a full str team with g2 luffy captain. Also you MUST replace kuro and sanji for whatever team you run against mihawk as 1/2 ATK will murder you.

As for ships, why not level up going merry? Max level has higher ATk increase than flying merry.

Do you really think he can beat mihawk with that team? He makes defenitly not enough Dmg. An 4* alvida would be good to survive

The suggestion I made for what could win included him needing to remove those 2 qcks and having a g2 luffy (which I kind of figure everyone has lol).
