Yes, but it will mean that FF VIII will turn out to be a pretty sad story and ppl might not be able to accept the fact that the happy ending they see in the ending FMV is just short lived.

I dun think it is a small fact because for what Laguna did to Adel delayed her plan for ten years if Adel is truly possessed by Ultimecia. And if she did possessed Adel, she will have succeed with her plans without having Squall to stop her ten years ago before the time of Edea which mean she truly defied fate as you mentioned before. Also as mentioned:

(Edea: "So you are the legendary SeeD destined to face me")
It show that she know/remember stuffs that is hindrance to her plans. And I do think how much of hindrance do Laguna's trap cause to her plans.

Also, if Adel is trapped in the Sorceress' memorial, and Ultimecia's consicous is inside her, will she most likely get trapped along as well? Since the machine is strong enough even to affect radio waves.
