Oolong Island vs. Mighty Avengers

This time, instead of the goal of driving Black Adam insane, Oolong Island's residents are put to the task of destroying the mighty avengers.

Do they win in any of the following scenarios? Prep is one-sided

1. One year prep
2. Half year prep
3. Two months prep
4. One month prep
5. One week prep
6. One week prep, MA also gets prep

?

sorry for ignorance, but what's Oolong Island?

Island from 52. Full with evil geniuses who've all got an unlimited budget.

Note: Assume that this battle takes place on Oolong Island, and that the scientists have full access to info on their opponents.

I'm going to go out on a limb here and say.
1.Yes 2. Yes 3.Yes 4. 5/5 5. No 6. No

But I'm just kinda guessing since I haven't been keeping up with 52. I think that given enough time with prep and having bio files and being on home turf is big enough advantage to a lot of people.

mmm
