That's not how I interpret DFSG §1 [1]:
"1. Free Redistribution
The license of a Debian component may not restrict any party from selling
or giving away the software as a component of an aggregate software
distribution containing programs from several different sources."

I think this applies to Debian Live DVDs.

It'd probably be doable, but there are also other downsides like e.g.
a doubled build-time.
