Could not agree more. I have heard the "beam down too fast so Keeper is giving an illusion" hypothesis before.
One thing I will say is IF Vina is still alive then they SHOULD tell her Pike is really coming down or else they will be in for a real shock when they discover human minds change over years and she will be able to pick up the differences between her fantasy Pike and the real Pike pretty fast I'd say.
If she had DIED, then Pike would have no way of knowing the deception as far as I can tell.
It's hard for me to see that in my mind though. I grew up reading the hell out of this issue (DC Comics Annual # 2, 1984):
It's for sale at mile high comics:
