The real issue with 6/8 or 12/8 support (especially in slower 6/8 or 12/8) is that chords often change on count 6 (or even a run up on beats 4, 5, and 6) and again on count 1, which BIAB then doesn't support. The only recourse there is to use a 3/4 waltz style, which doesn't necessarily have the feel of a 6/8 or 12/8 song.

A tripletized 4/4 style works great as long as the chords only change on counts 1, 4, 7, and 10.

I'm thinking, for example, "Great Is The Lord" by Michael W. Smith (see below).
