My other thought was to just to the same recipe and substitute the Mosaic for the Citra just to see what happens.
That's the best way to learn. Brew the same recipe, and tweak one thing at a time.
A few things I would do differently...
Take out the crystal malt. If you want the color/character substitute it with a german cara malt, or amber malt
You can use citra to bitter, i'd do a first wort addition with it. Save the 15 and 5 minute additions for a hop stand or whirlpool.
It seems to me like that recipe was designed around 2010-2015. A lot has changed since then!
For me, I believe citra and mosaic together is pretty bland - but when you add in a third hop like galaxy or some other trendy hop, it comes out real nice. Be careful when adding in the third hop, some hops perform better on the cold side. When I added galaxy as a bittering hop, I got a strong bitter menthol flavor from it. Galaxy is one of those hops that work best on the cold side. So if you do go with mosaic/citra/galaxy - use galaxy in cooled wort or as a dry hop.
