In general I agree with your assessment of copper vs. silver, but it doesn't always hold. I've definately found that using silver between the source and preamp and copper between the preamp and amp preserves much of the detail and transparency of the silver while filling out the mids--kind of the best of both worlds if you're suffering using all copper or all silver(see this month's soundstage.com review of Acoustic Zen cables for an example of this if you haven't already seen it). Haven't tried it the other way, but I bet you're correct that the silver can't put back what doesn't get to it in the first place.
That said, the best copper and silver cables I've heard seem to do just about everything right, but it comes at a price. I've found mixing copper and silver at a more budget level can be a way to achieve outstanding peformance without dropping a bundle. Best of luck.
