I'm probably not qualified and may even be answering a different question, but I ran into what I think was a similar problem and found a solution. I was looking for a style in what I consider to be 2/4 time (Trying to think of a sample and I came up with singing the alphabet -- A b C d E f G, like 1, 2, 1, 2, 1, 2, etc.) As in two accented beats per measure. I've used BIB for years and never put it together that, although the second column from the left in the style picker will read "4/4", when the third column (labeled "EV/SW" but also known as "feel") is set "EV16" I get that 2-beat feel. ("EV8" in that column is what I think of as 4/4 time.) I hope that helps.
