Wouldnt it be cool if apex had warzone custom weapon system?

The weapon level system that the game has right now is pretty useless. I think that it would be great if we could get weapon attachements like better meg, recoin and such by leveling or weapon, like in warzone, and also be able to pre custom or weapon with those attachements before entering the game. Even if we could do that only on Mix tapes modes it would be awesome
