I have no doubt that Reale (and Flyntz, Moore, etc.) could pull together a Thundersteel pt. 2 and get away with it. They are very analytical and versatile songwriters.
The question is whether it's a good idea. Hopefully it's a higher priority to bring the Riot live show to some starving cities and nations than to make an album.
That all said, I will take all that I can get from Riot!
