Alternative Full Weapon Models

When i first saw the Weapon Model option in the Weapons Bench, i honestly thought that down the track you’d be able to choose a variation of that weapon that had previously been in the franchise.
For example, being able to change Infinite’s Assault Rifle to the Halo 1 style or even a Banished version etc.
I really feel having this option would add a unique aesthetic option for Multiplayer. Even finding different variations during the campaign randomly would have players swapping weapons on the regular.

Also, being able to equip more than one Weapon Model piece to your weapons should be an option as well just on a side note.
