"I tried to make a new design for the center crosshair icon to fit the original Portal 2 design aesthetic a little more. I don't know if I'm allowed to post the separate image files as a .zip, or if they'd even be usable in .PNG format, but I have them and can share them with anyone who wants to give modding it in a go.

Sadly, you can't have this in your game yet. Not unless you know how to navigate Source (I sure don't) and modify stuff like that. It's a tedious process.

Portal Reloaded's developer, Jannis Brinkmann, said that if he ever comes back to the project he'd be sure to consider it."
