Secret weapons discussion

So First off I think the secret scorpion can and should have a form or model if you will this would allow you to throw grenades in grab ledges when you have it equipped I would also bring back the Scarab Skull from Halo 2 plus I would add a Wraith Skull and Mining Laser Skull obviously the Wraith Skull would make all weapons shoot Wraith rounds and the Mining Laser Skull would make all weapons shoot mining lasers like the one there at the dig site in Halo Infinite what do you all think of these ideas I noticed there’s not a lot of people replying to this I guess they don’t like these ideas of mine
