What is the purpose of your RAID0 - why do you want to change the chunk-size and how many physical disks are involved or available? –  Nils Aug 27 '11 at 20:21

It depends on kernel version and mdadm version. The fastest way to check is to search mdadm manual for chunk-size. mdadm manual from Fedora 15 has a CHUNK-SIZE AND LAYOUT CHANGES section.

You can make it a raid 10 with a new raid0 that has your wantet chunk-size. After that you can degrade to raid0 again.
