No. It's a stupid idea.
You feel you should have more weapons to choose from. Greater variety. That's fine, but what about the armor? Why should the legendary armor be rendered irrelevant?
So now we'll have a level 32/33 difficulty setting for Vault of Glass and upgraded weapons and armor to go along with it (since you shouldn't be able to upgrade your existing gear -- you should have to run Vault of Glass all over again to get them).
.. why would anyone do Crota's End at that point? All the Vault of Glass weapons are better than the Crota's End weapons, with the sole exception of Hunger of Crota.
New content, specifically new raids, need to give players and incentive to do them. If you can run Vault of Glass for better gear, what's the incentive to run Crota's End?

Precisely. This is why I think that in each new raid, there should be a chance to have a material drop. This material will be specific to the raid, and once one amounts enough, they may upgrade the gear from the previous rad to the new cap, wiping upgrade progress like the current exotic upgrade method.
