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).

thanks,
