Your are correct, it would look a bit weird, but going with the elbow idea and using copper tubing to locate a gauge elsewhere, like in the main panel somewhere would be OK. I am not sure about the space behind those panels and if there is enough space to do it.
Watching the brew boiler pressure drop (slowly) to my 2 bars of line pressure while pre-infusing seems to help in the taste department.
