For those edges you can just make them a different material id and use the VrayMultisubobject Map and make the edges more glossy, that will give the right general effect (or bump map it - either way).
I agree that getting too hung up on 'physically correct' can be a hassle, but the more cheats and hacks you add to a scene the less intuitive it becomes to light and work with it, and the less your assets become useful for other scenes. I use plenty of cheats too, but I do try to keep things "realistic" simply because it tends to make everything simpler and less error prone.
YMMV.
