Can you be specific? Do you mean like a C-E-Gb-G? Wouldn't that end up translating to some form of inversion of the F#-A-C-E-G (without the A obviously)... So in a hypothetical situation it could be a half diminished vii43 chord without the third? I'm amusing myself trying to understand what you mean, and I ended up with that. I tried avoiding having the same letter name twice.If anyone follows me, or knows a more proper name for that, then please explain lol.
