Couldn't agree more. This kind of thing could be very cool for all the factions and would make customization really personal and interesting. Plus, given that the devs have talked about 'horizontal' progression, this is a really effective way of showing off your skills.
There was also a suggestion going for the if you play the game and do stuff idk what, your gear becomes relic in the end, so a regular customized bolter can be a relic bolter in the end after playing and doing the missions or so, it was an idea that was posted by a dev.
That would be the equivalent of relic, possessed weapons and the like, but it was an idea only at this point, but a very good idea none the less.
I pray for as many customization options and features as only devs could realize. I'd also like to participate in the fanart contest for in-game weapons/armour design, really would love to see such a community involvement rather to see that option for 2,5-10k$ like some other games did.
I think it'd be cool to have chains spikey bits, but also cracks in armour, and scars/tattoos on faces(remember some of these guys are more than 10,000 years old, I don't care how badass you are you're going to show some wear and tear after fighting for that long) and inscribed cloth/flayed skin on shoulder pads and whatnot.
