No. 'Bios' is something you introduced in your post:

What I wish to know is if it is possible to add specific profile fields (tabs) to the mini-profile bar in all posts. So, if I created a profile field called 'Bio', would I be able to have this show in the mini-profile bar (in posts) of all members (preferably, only those who have made use of 'Bio')?
And, if it is possible, is it purely a link, or a popup (which would be much more useful)?
This or something like would be useful I think. Trying to do something similar to you had already crossed my mind. But now that you describe the difficulties, I am glad I did not attempt it. But yeah, I am on board with the idea of a sticky menu bar.
