Is mix FSAS and SAS disks in one aggregate possible?

So we have a
1 *FAS2750 with 20 *1.8TB(X343)
2 *DS212C with 10 *8TB(X318) each
After using 6 *1.8TB disks for root aggregate, can I put all remaining drives in the same aggregate?

I tried with -allow-mixed-rpm, it won't work, show errors: "Error: command failed: Addition of disks would fail for aggregate "aggr1_02" on node "cluster1-02". Reason: Disk type does not match type of disks in the aggregate.";
I found this KB:"How to add larger capacity disks to a RAID group that contains smaller capacity disks - NetApp Knowledge Base", and tried the "Scenario 4: A new RAID group is created in the aggregate to ensure that similar size drives remain in the same RAID group", and got errors too:"aggr add: There are not enough spare disks with matching disk type. 20 disks needed from Pool0, but no matching disks of the requested size are available in that pool.";
also tried "storage raid-options modify -name raid.mix.hdd.rpm.performance -node * -value off" still won't work.
So is mix FSAS and SAS disks in one aggregate possible?
