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).

Note that your NAS is going to take at least 2 sync's for the first drive and three for the second. I say "at least" because it could be more if you originally started with some drives even smaller. The NAS will report in the log that the sync is complete, but it's not. Only the first one is. Make sure all sync activity is complete before you replace the second drive.
