No, I've never gotten around to it.  I do use the Sophia.  But, believe it or not, I still haven't gotten around to putting it in a tank.  I've been using it as a dripper so far.
I'm very, very, very slow to do new things.
As a matter of fact, I had just come online to ....* about RBAs when I saw your post.  I don't have the greatest eyes and get frustrated very easily.  I frequently work on an RBA for a while, then get too frustrated and just put it away.  This time it was a Mini EK clone.
Actually, the Sophia is very easy to build.  Very surprising considering how small it is.  I really like the ceramic cup design.
Ooh, I just thought of the perfect tank for the Diver V2!  I don't have many 35 mm 
tanks.  I just broke my favorite one.  But, I just remembered a plastic one I have put away. As soon as I find it, I'll give it a try with the Diver V2.
