Yes, that will work. Assuming you are using X-RAID, then 2x10TB+2x16TB will give you 36 TB of storage (reported as ~32.75 TiB by the web UI). The resync will take a while, and the second resync will take longer quite a bit longer than the first.
Netgear recommends making sure you have an up-to-date backup before manipulating the disks (and FWIW, I agree with them on this). There is no RAID redundancy during the resync, so if one of the original disks fails during the process you will lose your data.
I also recommend testing the new disks in a Windows PC before putting them into the NAS. I always run the long non-destructive test, and follow that up with a full erase test. I have had some new drives pass one of these tests, but fail the other.
FWIW, the first resync will require 33 TB of disk I/O, the second will need 52 TB, so 85 TB in total. Doing a factory default with 2x10TB+2x16TB disks in place would require only 52 TB of disk I/O to create the volume, plus the I/O needed to restore the data from backup. So the factory default would be faster then one-by-one replacement (though it would require more manual steps).

Backup.. Remember back when i used WD disks.. Always when swapping disk to upgrade.. some of the other drives died in process, so had start all over.. But since i have online backup, all was ok.
Since i started using Seagate Wolf disk.. haven't lost one. Seems like the quality and price are both better 🙂
Yesterday i swapped last 3TB for the 16TB. Takes time for sure, but all looks good đź‘Ś
