Can I create two volumes, RAID1 and RAID0 on two disk NAS326?

I currently have 2 disks in my NAS and RAID1 volume but running out of space. My idea is to have a RAID1 volume to keep the data that requires more protection and RAID0 for other data. I can't just do it from web-GUI, but I see a software RAID on my NAS, md0 for system, md1 for swap and md2 for data. So the idea is

* shrink ext4 on /dev/md2
* shrink md2 RAID1 using mdadm -G
* create fourth partition on each HDD (fdisk) and a RAID0 on them (mdadm).
* add a startup script to assemble and moint this RAID0 as /dev/md3.

Could anything be wrong with it, e.g. a configuration conflict or hard-coded requirement to have exactly 3 partitions on each internal storage will makes the device fail to find installed applications, etc?

    You can't configure both RAID types at the same two disks due to both types need two disks respectively. Therefore, you need four disks to create RAID 0 and RAID 1
