Yes, I already added German audio tracks to my copies of your AVCHD Despecialized Editions of SW and TESB and it worked perfectly fine for me. Although I used to love the "Krieg der Sterne"-logo, I'm also fine with the original opening crawl and English subtitles because most of our official DVD- or BR-releases don't provide written text that's translated into local language either.
AFAIK someone is just working on this issue (German intro + text crawl + alien languages).
