Roll your own for now. I haven't started doing any significant btrfs
specific work on it but the initramfs builder in my project
http://underdog.sourceforge.net might get you past your problem pretty
easily for now. It would be easy to white/black list which devices you
want to submit to scan or mount.
It is plumbed up to look at each storage region one-by-one so you could
assemble your file system that way.
(Note that the eventual point of the project isn't really the initramfs
stuff but that's what I needed more/first.)
It's fairly well documented and I use it for some non-trivially complex
systems but its not (yet) so complex that it's hard to design hooks for it.
