Sorta related. Woops and totally off-topic.
My canon Warden was an Elf mage that romanced Alistair. Long story short I have never done a DAI PT with that world state because well Hawke or Alistair, how can I choose? Anyways my Archer Adaar has that world state from Origins because I used a male Hawke that isn't as important to me as my purple Lady Hawke. I never watched any videos of Warden Alistair in DAI so I was grinning like a fool last night when I finally went to Crestwood. I did the dark ritual with Morrigan and it was really great seeing Alistair meet his son. My sappy little heart was going all a pitter patter when he talked about my Warden and how much he loves her. Awwwww been so long since I've had the Alistair feels. I sided with the Templars though so I feel horrible that his mother is dead ><.
How could you?! 
Eh, to each their own. My "canon" worldstate is a City Elf who romanced Alistair, left him a Warden, then had him perform the Dark Ritual with Morrigan. My "canon" Inquisitor also sided with the mages, because, well... Dalish elven mage. To me, choosing between Alistair and Hawke is easy because I love Alistair but could care less about Hawke. 
The only issue is, on my first playthrough I got through Adamant before Wicked Eyes and Wicked Hearts. First I was just rushing to meet Alistair because my girl hero-worshipped him and the Warden, then I thought, "OMG, demon army! Gotta stop that right away." But I didn't know that Alistair would leave Skyhold right after Adamanent, then Morrigan joined right after Wicked Eyes (along with her son), and I thought, "Oh... I wish Alistair was here to see his son!"
In my "perfectionist playthrough" I intend to have them meet, but I'm not sure when to do Wicked Eyes. I did it last in my first playthrough, and it seemed fitting somehow. I feel like if I do Wicked Eyes before Adamant, it should be before seeing Erimond in the Western Approach, since it seems wrong to just let him rest and recoup with a demon army inside Adamant while I attend an Orlesian Ball. Then again, if I headcanon that the Orlesian Ball date just happened to be just after he got into Adamant, and the Inquisitor couldn't miss it for anything and Inquisition forces are searching for a way into Adamant while at the ball, maybe it's not so bad... *grumble grumble*
