Painful Isaac, the nightmare of every paper modeler. I agree with Gary, you saved the model very well. I wouldn't worry too much about the off-colors. They don't show that much as such in the pictures. Most important thing is that it fits right now.
Regarding the bin temptation (a different kind of temptation compared to the nose lady with her merchandise exposed so openly), I once smashed a B747-300 after quite a few frustrating hours of misfits, too thick paper, off-colors in the print (KLM-blue....), glue stains, and I admit, my own inexperience with complicated models. And you know what, it was a big relief, but most important, one learns best from own mistakes

Cheers,
