*So* glad you enjoyed Ancillary Justice! If your attention flags in Ancillary Sword--and it may not; there's a lot to love there--do soldier on to Ancillary Mercy because Whoa! And yeah, I think Ancillary Justice does have oceans to say about identity, but I'd never thought of that aspect you mention, trapping people in various facets of yourself (though of course as you say it, I can totally see it), so I'll be very interested in your thoughts when you share.
