Yeah, just use a key with those notes (the root notes anyway).
E Phrygian would work well. E Locrian too. OR, if you want to get exotic, Locrian #6 (harmonic minor, mode 2), or Locrian dim7 (b7).
If it's a jazz sound, try something like Dorian b2 (melodic minor, mode 2). Super Locrian also works, but there would probably have the guitar(s) doing third chords instead of powerchords.

Only Ash Remains by Necrophagist should give you some or ideas.
