...Since you were curious about getting control props to play nice with morphs, a query you had on the 11 technical forum... I'll give you my thoughts here, seeing how the question relates to your figure dev.

Yes it can be done. I did it years ago with a breast morph pack I made for LF. Simply morph the chips into position as desired for the relative morph and apply the match centers command including the bone and prop in the calculation. In this example I morphed LF's breasts and con props. The con props are shown visible, opaque, and red with the origins for the props displayed in this animated demo image... as you can see prop's origins follow the new position relative to the morph

Hope this helps ;)
