Is there a reason besides logistics that you don't want to do the Rogue upgrade? I think that would be the most cost-effective way to go. That and replacing the power tubes with KT-120s, which will give you more extension both on top and bottom. But if you don't have a dealer to go through, I can see why it might not be an attractive option.
I'd also suggest trying different 12ax7s to get a midrange more to your liking.
