As Aabeck points out, there is a VERY SPECIFIC type of transformer you can add to the system to do what you are proposing. There is a part of me that doesn't even want to refer to that as a transformer but what else would you call it?
However, if you are talking about using the neutral of a 480V/240V delta/wye isolated winding transformer as the neutral for the 480V delta system, that won't work for the reasons stated; namely the primary and secondary are still isolated from each other. The neutral means nothing to the primary side.
