you would have to turn off the HUD system thru scripting and then use the sprite system instead.
This can be done, But you will need to make the sprites, and the scripts to control it.
Take a search thru the script thread and check out some of the sprite scripts.
The radar.lua and the objective scripts in the scriptbank folder or maybe in the scriptbank\radar folder is a great example on how to set up the sprites.
