JBOD to X-RAID2 on a 104
I have a RN104 with a 4Tb drive (6.2.0) (currently pretty full, 525GB free of 3.49TB, but I may be able to free ~1.6 TB). I am waiting for delivery of 2 x 4TB (WD-Red). I wish to have a simple X-RAID...

If you manually changed to flexraid, then you can simply change that back right now. There is no extra overhead.
If you never did that, then you are already running xraid2 (just with one disk).
Hot inserting is recommended, as that makes it very clear to the firmware that a new disk is being inserted. You can insert both at once, though I generally do one at a time (waiting for the resync to complete). Either way it will process one disk at a time.
The first disk will convert your existing volume to single redundancy, so there is no space gain. The second disk will increase the volume to 8 TB - which will be shown in the web ui as ~ 7 TiB.
There is no need to free up data first (the expansion process operates on the physical disks, so an empty volume takes the same processing time as a full one).
Always a good idea to update your backup before inserting disks.
