Yeah I get you, when I was messing with this stuff a while ago I do remember something about sweeping child components but can’t remember if it was you could or couldn’t do it a certain way, so I guess I’ll just take your word for it.
The way mine works is by welding the physics objects to the motion controller component so I believe they should get the late updates this also means that any collision still works as it is just the physics system doing the hit detection.
