I think you’d be creating more of a hazard trying to attach a mask to you BCD and it’s worth. I’ve dove in many high current situations, never did I feel my mask would every come off my face. Diving with divers unaware of others around them...that’s a different story. In that case, I do my best to give myself space, and if they happen to be my buddy (and I need to keep them close due to low visibility situations) I just try and be mindful that my mask or even my regulator might get kicked or grabbed with a hand inadvertently, it’s just an inherent risk we take when we go down, giving others space I think will give you peace of mind at least with the destinations you mentioned as they all have great visibility.
