Free time stack

So I am a legacy member, and I was thinking I was only getting the 14 days for free, and I was cool with that.

When I logged into my mog station it even said I have 14 days free. Makes sense. How ever I just put in my CE PS3 code and when I refreshed it is now saying i got 44 days free. Which also makes sense 14 + 30 = 44, I was just under the assumption I wasn't allowed to get the free 30 days since I am legacy.

So now onto my main question, seeing as how my PS3 collectors edition time stacked, could I put in my other PC collectors edition reg. code? and get 14 + 30 + 30? for 74 free days?

Edit -------------

I also noticed on the mog station since it was my first time being on it since they implemented it.

Do you have to log into your mog station and unlock the veteran rewards once you are allowed to get them? I mean there cool and all, but there not good enough that I think I would waste my time logging into the mog station to unlock them. I was under the assumption it was a very simple transaction. After you pay your time they would just send you the item in the mog mail.
