Doubtful, In my years at the electric company down here in MA and from what I've seen working out of town, a utility generally won't change anything unless it burns up on their end. We used to use #4 aluminum and our standard now for residential is #2 aluminum or 1/0 for high draw customers. but if you have an existing #4 or #2 service they likely won't change it no matter how big a service you put in. Utilities get away with it because of open air rules for conductors and their ability to dissipate heat more easily.
