Nope, it's the opposite, in fact. You confuse devaluation with depreciation. What should really happen is that Germany's currency should devaluate (via inflation).
I think of it as this: GIPS have massive debts in "German"-Euros. They also have prices too high in "Gypsy"-Euros, which is equivalent to say that GIPS have also salaries too low in "German"-Euros. They just can't pay that debt, because Gypsy salaries are too low, the prices are proportionately too high, and the debts are also too big.
What you do is, you create inflation only in Germany. Now German Euros are valued less, so wages and revenues grow. Gipsy Euros are valued the same as they were, so prices stay the same, and wages and revenues stay the same.
Now, this means that Germans want to buy more cheap Gypsy stuff and services, so there's now a trade deficit for Germany, and a trade surplus for the Gypsies. Which means an increase in wages and revenues for the GIPS, which is allocated to paying German debt.
The result is that the Gypsies get German jobs and German capital, and the Germans get their debt paid. This debt is, of course, of less value now for the Germans, they have to pay more for everything German, and there's less jobs on Germany, so they are pissed off. The thing is, they still win on the long term, because now they can buy cheaper Gypsy stuff, like Spanish-built German-designed cars. They can concentrate on more capital-intensive production, to offset lost jobs. Also, at least, they got back some of their debt.
