It should work fine but the write speeds (and fsync/sec) will typically be the slowest of the two.
I use a NVME M.2 mirrored by two SATA drives for my VMs, which I think is quite similar.
Older systems sometimes cannot boot from NVME (PCIe). You might want to make sure, otherwise the redundancy won't help if the SATA one fails.
