Returning Player - Expansion issues

Ok, so I already have the base game and an active subscription.

If I buy Stormblood Collectors edition, I only get Stormblood Collector's items and no Heavensword Collector's items.

If I buy the complete collector's edition, I get all Collector's items from base game through to Stormblood.

My question is, seeing as I would be applying this complete collector's edition to an already existing and active base game account, what will happen?

The mog station should recognize it for what it is and give you the all appropriate upgrades.

But it might be cheaper to get regular Stormblood and then do a full digital upgrade. Stormblood at MSRP is $40 and the full digital upgrade for ARR+HW+SB all at once is $40.

The complete collector's edition MSRP is $100.
