Unfortunately, no. I don't have the sk1llz to do that, I'd either need to figure out the edges, or figure out some way of rendering the mesh so that it didn't completely cover the ship. And whatever method used would have to differentiate between the shield quadrants, which would be a pain in the ass or nigh impossible, depending on how the shield quadrant is divided up.
Re Goob:
This isn't really a graphical improvement, it's more of a replacement in case someone doesn't want to make/use an ANI for a shielded ship. It'd be fine to just have it switch on if no shield ANI were present and a ship had shields, except that's how the support ships are in Retail FS2.
