I too am brown.  Again the non-stereotypical type.  I don’t have any direct experience with this, but what if you just removed the RPi?  Then it’s just a monitor and you shouldn’t have to even pull it out of your carry-on.  Chances are they’ll inspect regardless, but you shouldn’t have any major issues.  You can clearly see where all the wires are going.   good luck!
