C/E works well in BIAB, I may go with that. It didn't work so well on the keyboard where I was trying to work on it. For some reason I never tried the C in BIAB.

D chords ( II ) are not that unusual in C. The VII chord is common in rock music and V7 is very common. All have accidental notes.

An Em7 seems to work in BIAB also. I think getting the right inversion has a lot to do with it.
