Just to bring conclusion to this. I ended up sourcing a couple of 8TB drives locally for a decent price and had those rebuild the failed drives, then swapped each parity drive 1x1.

They are no longer detected. I've checked all cables, but those 2 drives do not sound healthy when power is applied. So I would connect the 2 new drives to replace the failed drives, follow the parity swap procedure. Perfect, just wanted to ensure I could do both at the same time! Thank you for your help.

I have an array of 16 drives and 2 parity drives. I have a situation where I had a failed drive and ordered a few larger drives that I planned on upgrading the parity drives and then replacing the failed drive. Now a second drive has failed as I wait for the replacement drives to arrive. Unfortunately the drives I have sourced are larger than my parity drives. What is the correct method to swap out both parity drives for the larger drives and replace the failed drives with the current parity drives? It seemed fairly straightforward to do the parity swap with one drive, just want to make sure I don't make a stupid mistake with a second drive now having issues.
