I'm not sure everybody absorbs this aspect of your question, Rach...
Is your premise that this is about CDers who will ultimately transition in some way? If so, I could only imagine you will receive affirmation that folk do ultimately want to be seen as a woman because that is who they feel they are inside.
Outside of transitioning TG/CD folk, we clearly have people who CD but have no desire to blend in, but this is about them presenting as they feel they both need and have a right to, without offending anyone... so in the generic CD world I think we have a mix of motivations, from very mixed gender presentations right through to social cosplayers and DQs who may look passable or a parody of female presentation, but whose motivations are quite different.
If you're cross-living, then I would have expected passing = presenting as who you really are..
