Eh, I think it's normal to not have plans for Accel considering how he's not involved in dark side stuff by now and going after him is suicide, I mean, it's not like you can have any plan except; Step 1. Don't antagonize him Step 2. Run the fuck away.
Not having plans for someone like Mugino or Kakine who are active in the Dark Side would be dumb though.
For everyone else, the #3 is a goody-two-shoes who you never expect to appear in the dark side, the #5 has no actual counterplay and anyone who knows or sees her doing shit would just get mind erase'd.
And planning for Gunha is pointless.
