Yes you can use that HUD layer and modify it for your use.
BOTR has the right solution for what you want without setting up your own rig.
Which is pretty simple. Set a skeleton or bones rig with the intended eyes at the 0,0,0 point in 3d space.
This is where the HUD camera in GameGuru is focused on.
Attach to arms to the rig, then attach which weapon to the rig, and animate what your movements need to be.
Export it as a HUD Layer x file with animation, and test it out in Game Guru.
