Can CBBE armours be manually converted in Bodyslide to 3BA, so that they take 3BA sliders?

As title.

I have a strange anomaly -- there's a set of CBBE armors that don't take 3BA sliders, with just the 1 exception. I can't figure out why there's just this 1 exception.

Is there a way to make them all take 3BA sliders?
