If "Frangleterre" (Franco-British Union) had become a reality

MartelFirst:
There have been some "recent" (~century old) proposals to unite both countries (never taken very seriously though), so here I imagined if it were a reality, with current numbers for GDP and population and whatnot, sourced with wikipedia.
Also; sorry, I realized after that the map I chose doesn't represent Kosovo.
I chose things like population and all to only include "in Europe", because the stats I found make it all difficult as often they give for example France's total population but excluding some overseas territories and whatnot. I wanted to thus focus on Europe, except for GDP and for the EEZ of course.
