Personally, I would use the exact same HUD as seen in the original MWO / MW5 trailer if I could. It's so clean and simple and beautiful. Maybe not super-practical. The lack of colours makes it a bit harder to read speed and heat, sure. You can't see any geographical features on the minimap, it's just a radar. You can only see paperdolls when you or your target is taking damage. You can only see your weapons list when you're firing your weapons.
It's not perfect. But I would be so thrilled if I at least had the choice to minimalize the HUD. What we have now is quite practical and good, but it detracts too much from the visual experience. Any time you see people taking screenshots or making videos, they rarely include the HUD. They just show the cockpit with HUD disabled, because the cockpit has so much clutter. But the HUD in that trailer looks amazing!
And yeah, I know the trailer HUD wasn't designed to be functional in a game. But I would still love the option to customize my HUD.
Even Descent Freespace had this option in in 1998, I believe. You could even change the colour of the HUD. Amber, cyan or white, I think. And in Freespace 2, you could have any colour you wanted. My memory fails me, but my point is, I think it should be doable
