If you can search the mailing list archives, there is more detail on how to do this, but what I remember of it goes like this:
Build a separate AMANDA configuration for each tape drive, and get them working separately. Configure one to only do level 0, and the other to never do level 0. Then change them to use a common backup database. You will then be able to search that database when restoring. One caveat: If you have a large change in your file systems, it might not fit on your smaller tapes, forcing level 2 or even level 3 backups. You'll want to keep an eye on that for the first couple cycles, and during any major disk activity later.
