Why do you want to RAID in first place then? RAID-0 is the only option
that doesn't lose space, but it increases your risk for the benefit of
performance.  Since you don't need performance there is no point in
taking the risk, much less the bootstrapping hassle.

You cannot convert existing filesystems to raid without first moving
the data somewhere.
