Should editing certain Hud elements be allowed? Such as the crosshair, and save/load game text, and maybe the weapon scope reticles. I think the crosshair wouldn't be harmful as its easily accessible to edit, and the crosshair is awful, but I'm not really knowledgeable on the other stuff to know if it affects the game in any way.

This is probably more into Liam's territory, but I personally don't care about changing the crosshairs or some other HUD elements. I'd say go for it, as long as whatever you change doesn't give you information you wouldn't have normally.
