I'd steer away from naming everything to their own. As the differences aren't that great (hopefully) to show up in epic scale. Also it would make the remembering of stats harder. If there is a reason why some weapons should be better then yes it could be done, but I think that it should not be done lightly.
There may be some justifcation for it with the warrior-to-carnifex venom cannons, which really do have a very distinct strength difference in 40k.
I think calling the Carnifex's cannon a 'Twin Venom Cannon' could overcome that though (Giving it +1 to hit without messing with the naming conventions...)
Not sure it's worth it however. 
Where's Jaldon?
