Please post your configuration and explain what you're trying to do in
more detail.

You don't put LVs directly ontop of RAID0, you put them in VGs, which
reside in PVs, which reside on disks or RAIDs, or iSCSI LUNs, etc.

It sounds like you have two filesystems, each in their own LV.  You
want to move them off a RAID10 (four disks, in two mirrored PAIRS,
stripped across them is what I assume), because why?

Give more details.  You do realize that while you will gain space, you
will lose reliability with RAID0, if one disk fails, all your data is
