I’m willing to try, but I fear you are going to end up going down a rabbit hole of needing to physically redesign the cockpit. Physically splitting the MFDs up and placing them forward, to the sides, and a little bit down is what I think will end up needing to happen to make this truly work.
For combat mode, I would like to suggest that instead of filtering things not on the list completely out of the hud, have their icon reduced to an approximately 20 pixel size dot. While that might not seem like enough to bother with, couple it with it’s local relative movement and you should be able to distinguish it from something like a background star fairly easily.
I think there will still be a high desirability to have an alternate weapon fire option within any given weapons group. Though given previous changes where you can’t fire both at the same time, this is certainly a logical change. Recommend flexibility on this as it really only became a problem with capital ships and multiple different weapons with different projectile velocities.
