Again, thanks for the help!

You have Zoro Lion's Song to beat Monster Chopper and Nami Happiness Punch to beat Coby V2 and Helmeppo V2.

If you Evolve also Mihawk you have all you need, here a Video to beat Coby V2 and Helmeppo V2 with a double Mihawk Slasher Crew:



^^

Thanks for the help Ciro! But, sadly, I don't have Happiness Punch/Towel Nami

Ohh you are right, make a good thing, evolve your Mihawk quickly. ^^

Ok! Again, thanks for the help!

Man evolve your ballon ruffy to gear 3. He will be your joker in every fortnight or against every raid boss. Also you can compensate the missing towel nami with your 5* Vista. You can go with Vista,robin,bp chopper,buggy and Mr3/golden pound against coby helmeppo.

Ok, thanks Mystogan! But, should I use Vista/Vista or Towel Nami/Vista as captains?

Using Vista/Vista you wil clear the fortnight like a normal story isle. 
To show you how easy it is with double Vista look here:

Ok, thanks!

With the characters I have, should I make anyone other teams for future events?

Nice video thx Mystogan.
Kaosctrl510 as Mystogan said evolve your Balloon Luffy to Luffy G3 as soon as possible to have a new Crew based on real power.

^^

Ok!

Is it possible for me to somehow use an Edward Newgate, Jozu, or Killer team against Monster Chopper?

Sure all 3 Crews work well against Monster Chopper 40 Stamina:
