convert raid-10 to raid-0?

Please CC me on any replies as I am not subscribed to this list. Thanks.

Is it possible to convert an existing 4-disk btrfs volume created as
raid-10 to a btrfs raid-0/striped volume?

i've got a btrfs raid-10 volume made with 4x1TB drives that's running
out of space, and i'd prefer not to reformat it if i don't have to.

   There's a GSoC student due to be working on this over the summer.
(I was looking at it, but I've stopped to give the student a clear run
at it).

good to know it's on the roadmap...unfortunately, it won't be soon
enough for me. i'll have to either reformat or add more drive(s).
