Weapons Modifications and Skins

I have 2 main questions.

First one, I would like to know if it will be possible to actually change some of the special actions on weapon and secondaries. For example, put a sight on the Lucius patern lasgun or remove it to have ironsight on the infantry lasgun. Add bayonet or removing it. It would be a real addition to the game if not.

Second question, I’ve noticed that skins applied doesn’t change the utility of the weapon. On the Lucius patern Mk III you can put the Mk I skin on it, and still have the “weird” bayonet attack that is different from the other variants. I was wondering if there will be skins of variants to apply, so a skin of Mk III that you can put on Mk I and still have the “better” bayonet attack.

I’d love to have my infantry lasgun ironsight and bayonet to better slain Herertics !
